The use of Titanium

Currently, the production of titanium metal industry is to be Raul law, products of titanium sponge. Preparation is the traditional process of titanium sponge titanium by cast into ingots, and then processed titanium. Click the main steps to be made from titanium mining is the process:

Titanium -> Mining -> Beneficiation -> too concentrate -> enrichment -> Ti-rich material -> Chloride -> crude TiCl4-> Refined -> Pure TiCl4-> magnesium reduction -> titanium sponge -> Casting -> titanium ingots -> processing -> titanium or titanium parts if the above steps to get the rutile mining, enrichment is not necessary to go through, you can take direct chlorination of crude TiCI4. In addition, the casting operation should be a metallurgical process, but sometimes also included processes.

The above-described process refers to the process in terms of plastic working and casting. The plastic working method also includes forging, extruding, rolling, drawing and the like. It can be processed into a variety of sizes of titanium ingots cake timber, rings, plates, tubes, rods, profiles and other products, can also be made into various shapes casting parts, components.
Titanium and seamless titanium tube alloys have a large deformation resistance plastic processing; room temperature plasticity poor, yield strength and ultimate strength ratio is high, big rebound, notch sensitivity, deformation process easy and die bonding, heating time and easy adsorption of harmful gases and other characteristics, plastic working than steel, copper difficult.

Therefore, processing of titanium and titanium alloys thereof must consider these characteristics.

Titanium uses plastic processing, plus unlimited land size, but also to mass production, but a large amount of scrap lumber remnant low processing. Principles of titanium production process shown in Figure 1-1.

In response to these shortcomings medical titanium plastic processing, in recent years the development of titanium powder metallurgy process. Titanium powder metallurgy process and the same common powder metallurgy, the sintering must be carried out only under vacuum. It is suitable for the production of large quantities almost, small parts, especially for the production of complex parts. This method is almost no longer been processed, finished product rate, can make full use of titanium as raw material waste, and can reduce production costs, but can not produce large-size titanium member. Titanium powder metallurgy process: titanium powder (or titanium alloy powder) -> Screening -> Hybrid -> press forming -> Sintering -> Accessories -> titanium products.

titanium bars Production Process principles

In addition to titanium titanium, but the world has produced nearly 30 kinds of grades of titanium. The most widely used titanium alloy is Ti-6Al-4V, Ti-5Al-2.5Sn like. Our common titanium alloys and its components, as shown in Table 8-9.

Titanium compounds and uses

Important titanium compounds include: titanium dioxide (TiO2), titanium tetrachloride (TiCl4), partial barium titanate (BaTiO3).

Pure titanium dioxide is white powder, is an excellent white pigment, trade name "Titanium White." It combines white lead (PbCO3) covering performance and zinc white (ZnO) lasting performance. Therefore, it is often added to grade 2 titanium wire dioxide in the paint, white paint made from advanced; in the paper industry as a filler added to the pulp; the textile industry as rayon matting agent; on glass, ceramic, enamel industry as additives to improve their performance; used as a catalyst in many chemical reactions. In today's growing chemical industry, titanium dioxide and titanium compounds as fine chemical products, with high added value, the prospects are very attractive. Titanium tetrachloride is a colorless liquid; mp 250K, the boiling point of 409K, there are prepared odorous. It is in water or moist air are easily hydrolyzed, smoke a lot of white smoke.

TiCl4 + 3H2O == H2TiO3 + 4HCl

Therefore TiCl4 in the military as artificial aerosols, which are still used in marine warfare. In agriculture, the formation of fog covered it with TiCl4 ground floor at night to reduce heat loss, protect vegetables and crops from cold, frost damage.

The TiO2 and BaCO3 obtained partial melt together barium titanate:

TiO2 + BaCO3 == BaTiO3 ten CO2 & shy;

Artificial obtained BaTiO3 having a high dielectric constant, the capacitor made therefrom has a larger capacity, more importantly BaTiO3 significant "piezoelectric properties", the crystal under pressure will produce electricity, a power, and changes shape. People put it in the ultrasound, which will produce a current pressure, the intensity can be measured by measuring the current intensity of the ultrasound. Almost all of the ultrasonic instrument should be used to it. With the development and utilization of titanates, which more and more widely used to make non-linear element, an amplifier medium, computer memory device, the mini-capacitors, electroplating materials, aerospace materials, magnetic, semiconductor materials, optical instruments, reagents, etc. .

Titanium, thin titanium sheet alloys and titanium compounds excellent performance prompted urgent human needs them. However, high production costs, so the application is limited. We believe that in the near future, with the titanium smelting technology continues to improve and enhance the use of compounds of titanium, titanium and titanium will be greater development.

Characteristics of titanium and titanium alloys

Titanium is a silvery white metal, it has many excellent performance. The density of titanium was 4.54g / cm3, 43% lighter than steel, lighter than the prestigious magnesium slightly heavier. Mechanical strength of steel but with similar, more than twice as large as aluminum, magnesium than five times. Titanium, high temperature, the melting point of 1942K, higher than that of gold near 1000K, higher than that of steel nearly 500K.

Chemical properties of titanium alloy sheet are relatively active metal. Can be non-metallic effect with O2, N2, H2, S, and halogen when heated. However, at room temperature, dense titanium oxide surface protection film is easy to generate a very thin layer, can resist strong acid or aqua regia role, showing strong corrosion resistance. Thus, the general metal becomes riddled with acid, alkali, salt solution, and titanium are safe and sound.

Dissolve almost all of the liquid titanium metal, and a variety of metals can be formed alloy. Join prepared titanium steel titanium steel tough and elastic. Titanium metal Al, Sb, Be, Cr, Fe, etc. generated between interstitial compound or metal compound.

The same aircraft titanium bar for sale alloy aircraft heavier than other metals contained more than 100 passengers. Made submarines, both seawater corrosion resistance, but also anti-deep pressure, the dive depth increased by 80% compared to stainless steel submarine. Meanwhile, titanium rod for sale non-magnetic, not mine found, with good anti-guardianship role.

Vanadium has a "pro-biotic" 'sex. In the human body, can resist corrosion and non-toxic secretions, adapt to any sterilization methods. It is widely used in making medical devices, making artificial hip, knee, shoulder, threatening joints, skull, active heart valves, bone clip. When a new package in these muscles annulus "titanium-bone", these titanium bone began to maintain the body's normal activities.

Titanium is widely distributed in the body, in an amount of normal body weight not more than 70kg per 15mg, its role is unclear. But titanium can stimulate phagocytic cells, so that the immune system has been proven to enhance this effect.

Plastic processing technology and titanium Titanium's direction

Titanium plastic processing industry is a high energy consumption industries, hot rolling, annealing and heat treatment operations require higher energy consumption. Reduce energy consumption in the production of grade 1 titanium wire processing, help to reduce the cost and energy savings. Titanium way to solve the problem of high energy consumption in industrial production mainly rely on technological progress, improved technology, the development of energy-efficient technology, the development of automatic control technology, the development of energy-saving technologies titanium processing. Titanium plastic processing technology to achieve large-scale and continuous production process mechanization and automation, the process uses computer-controlled operation, in order to improve labor productivity. Large foreign titanium forgings overall use of 45kt or 75kt forging hydraulic press repression.
Plastic processing titanium and titanium alloys have large deformation resistance, poor room temperature ductility, yield strength and ultimate strength ratio is high, big rebound, notch sensitivity, deformation process easy and die bonding, heating time and easy absorption of harmful gases and other characteristics. Titanium plastic working than titanium, copper difficult. Titanium and titanium alloys processing must consider these characteristics thereof. Titanium and seamless titanium tube alloys using plastic processing, processing size is not limited, but also to mass production. Titanium processing plastic processing is the dominant approach, most of titanium products are produced using this method.
Currently, the traditional method of processing a titanium material mainly plastic processing, three methods of casting and powder metallurgy. Plastic machining process for titanium sponge titanium is cast into ingots, and then processed into titanium. The plastic working method comprising forging, rolling, extrusion, drawing, punching, spinning, etc., through which plastic working method may be processed into a variety of titanium ingot shapes and sizes of plates, tapes, ribbons, foils, tubes, rods, type, wire, forgings and stampings and other products.
Energy saving
From titanium and titanium alloy ingots to finished parts, the finished product was only 10% -20%, therefore, recycling residual titanium and its alloys become lower costs and expand critical applications. Titanium and titanium grade 2 sheet residual waste sources is very wide, titanium scrap titanium ingot produced (cut head, trimming and picking dander) about 5%; titanium processing timber residues generated (odd bits and scraps) accounted for about 40% ~ 60%; machined from titanium to titanium products produced residual titanium (feed head, corner crumbs) about 50% to 75%; waste is also a source of titanium products.
Due to a large amount of residual titanium scrap, utilization promising. Therefore, some countries have established a special scrap metal recycling companies, specializing in the comprehensive utilization of waste residue of titanium, using special equipment and technology, large-scale, highly automated engaged residual titanium scrap recycling.
Recycling of waste in the residual titanium, in particular to strengthen the management of residual titanium scrap, do not let the waste residual titanium mixed with varying degrees of oxidation. It is easy to be processed separately according to different types of residual titanium scrap following four cases:
(1) uncontaminated residual titanium, including processed odd bits and titanium scrap, a large quantity of good quality, you should try to add as titanium ingot melting material, doped titanium sponge titanium blocks squeezed into use, can reduce processing costs;
(2) Waste titanium sponge and titanium scrap massive head, different titanium scrap, its purity and composition, respectively ilmenite industry as alloying additions, or as raw material for the preparation of titanium powder;
(3) titanium powder and titanium powder endures, as the fireworks industry should knock agent, but also as a preparation of the aluminum industry, additives and titanium powder metallurgy products, raw materials;
(4) mixing or impurities of titanium shavings and waste can be processed into high-ilmenite titanium block, such as 70 ilmenite (titanium 70%). With the increase of ilmenite additives industry demand for high-titanium alloy to titanium scrap as the main raw material of high-titanium alloy, much of the market. Currently titanium scrap as raw material to produce high ilmenite million tons annual output has reached around the world.

TIP of titanium and titanium alloys

Titanium is a refractory metal of a light metal, a density of 4.5 g / cm3, 57% only of iron. Strength titanium alloy with high strength comparable to steel, but also has good heat resistance and low temperature performance, long-term work at certain alloy between 450 ℃ ~ 550 ℃ and minus 250 ℃.
Circular blade cutter suitable for milling material titanium, because they may be appropriate to change the main angle. As long as these cutters equipped with special blades and apply the correct cutting parameters, under normal circumstances can improve the stability and overall performance. Feed per tooth should be set to the minimum amount, which is crucial.

Titanium and titanium - titanium milling need the right conditions compared with most other metal materials processing, titanium processing requires not only higher, but more limited. This is because the alloy has metallurgical characteristics and material properties and cutting action may have a serious impact on the material itself. However, if you select the appropriate tools and use them correctly and in accordance with the requirements of the medical titanium alloy processing tools and configuration optimization to the best condition, then fully meet these requirements, and obtain satisfactory performance and perfect results. Many of the problems of traditional titanium metal processing encountered is not inevitable, as long as the properties of titanium to overcome the effects of the process, we can succeed.

Various properties of titanium parts and materials to become a powerful attraction, but many of the properties but also affect its workability. Titanium has excellent strength - weight ratio, which is usually only 60% of the density of steel. Titanium elastic coefficient lower than steel, so the texture is harder, better deflection. Erosion-resistant stainless steel is better than titanium, and low thermal conductivity. These properties mean that titanium metal in the process will produce higher and higher concentration of cutting force. It is prone to vibrations caused by the tremor occurred while cutting; and, it is easy to react with cutting tool materials in cutting Shihai, thus exacerbating the crater wear. In addition, its thermal conductivity is poor, mainly because of the heat in the cutting area, so the processing of titanium metal tool must have a high thermal hardness.

Stability is the key to success lies

Some machine shops find it difficult effective titanium processing, but this view does not represent the development trend of modern processing methods and tools. The difficulty, in part because of the titanium metal processing is an emerging technology, the lack of useful experience. In addition, the difficulties often associated with the operator's experience and expectations related, especially some people have become accustomed to cast iron or low-alloy steel and other materials, processing methods, the processing requirements of these materials is generally low. In contrast, it seems that titanium metal processing is more difficult, because they can not use the same tool during machining and at the same rate, and the tool life is also different. Even compared with some stainless steel, titanium metal processing difficulty also still high. While we can say that the processing of titanium must take different speeds and feed rates and certain precautions. In fact, most of the material compared with the material, titanium is also a fully machined directly. As long as titanium workpieces stable clamping firm, choosing the right tools, the right motivation, good working conditions, and is equipped with a shorter tool overhang of ISO 50 spindle, all problems will be solved - as long as the cutting tool correctly.

However, in actual milling, titanium required for processing is not easy to satisfy all of the conditions, because the ideal conditions do not always have stabilized. In addition, the shape of many parts of titanium alloy wire complex and may contain many fine or deep cavity, thin-walled, bevel and thin bracket. To be successful processing of these parts, you need to use a large overhang, small diameter tools, which will affect the stability of the tool. In the processing of titanium metal, are often easier to potential stability problems.

Must consider the vibration and heat

Non-ideal environment also includes other factors, one of which is that the majority of the current machine is IS0 40 spindle assembly. If the use of high-strength machines, can not long maintain a new knife state. In addition, if the part structure is more complex, usually difficult to effectively clamped. Of course, the challenge does not stop there, the cutting process is sometimes necessary for full slot milling, side cut or contour milling, all of which are likely (but not necessarily) the formation of vibration and poor cutting conditions. Importantly, when setting the machine, you must always pay attention to improve the stability of the trend in order to avoid vibration. Vibration can cause chipping blade, blade damage and produce the results unpredictable and inconsistent. An improved measure is to adopt a multi-stage clamping the part closer to the spindle to help offset the vibration.

Since titanium metal at a high temperature can maintain its hardness and strength, and thus the cutting edge will experience high forces and stresses, together with heat generated in the cutting zone, means that the work hardening is likely to occur, which causes some problems generating, particularly those affecting the subsequent cutting step. Therefore, choose the best indexable insert grades and geometries are critical to the success of the process. Past history has proven, fine-grained non-coated insert grades are very suitable for titanium metal processing; now insert grades have more PVD titanium coating can greatly improve performance.

To improve the liquid metal is poured medical grade titanium

Titanium and titanium alloy precision casting foundry in magnetic

To improve the liquid metal is poured into the mold but also by the pressure of the electromagnetic 

force to the liquid metal up to titanium alloy bar‍ achieve this is to magnetic casting. Its basic principle is the 

magnetic pump installed in the runner through the outer liquid metal to create a magnetic field; 

while the DC also introduced into this already established metal flow field, in the alternating 

magnetic field and electric field, forming a liquid metal flow of the same direction and the 

electromagnetic force, thereby increasing the pressure of the liquid metal filling the mold. This 

approach allows the flow rate of the metal in the cavity only by the flow rate of the sprue in the 

ram effect of the metal is increased from 2 to 2.5 times higher than the stationary casting. When 

using this method has several casting should be noted:

1 After pouring liquid metal into the runner must maintain the continuity of the metal flow, the 

middle can not stop there. So we must pay great attention to the runner to select the size of the 

design and the electromagnetic titanium spring wire‍ pump and current values.

2 magnetic pump should be placed as far as possible at the level of the runner, but this system can 

reduce the consumption of casting metal.

3 the mold is filled to a pressure of liquid metal in a magnetic pump is carried out at 0.01 ~ 

0.05MPa, so as to ensure that the liquid metal in the cavity to achieve the required flow rate, 

appears in the middle to avoid drying. After the mold is filled, magnetic pump pressure should be 

increased to 0.12 ~ 0.3MPa, in order to improve the casting feeding capacity to prevent the 

emergence of casting porosity.

4. gating system should be designed so that in the magnetic pump liquid metal within this part of 

the runner in the final solidification, which must be strictly established following the freezing 

order: Casting - Other gating system - the magnetic pump runner, because pressure magnetic pump 

liquid metal in a mold and then built into the magnetic pump can only be maintained in the liquid 

metal before the runner did not solidify. Cast researchers using this method in the lost wax cast 

ceramic shell leaves the body length of up to 260mm alloy compressor blades. Pouring liquid metal 

filling the cavity at a pressure blade solenoid pump condition 0.035 ~ 0.04MPa conducted under. This 

ensures that the flow rate of the molten metal in the cavity reaches 1.4 ~ 1.7m / s, thus ensuring 

the cast surface is not cold flow medical titanium plate‍ leaves the flow marks, good forming. This solves the centrifugal 

casting leaf blade is twisted body, the presence of cold traps and loose, the pass rate leaves the 

problem of low utilization factor and metal casting surface.‍

Alloying elements according medical titanium alloy

There are two isomeric titanium crystals: Below 882 ℃ for close-packed hexagonal structure α 

titanium, more than 882 ℃ for β titanium body-centered cubic. Alloying elements according to their 

effect on the phase transition temperature can be divided into three categories: ① stable α-phase, 

improving the phase transition temperature of the elements of α stabilizing element, aluminum, 

carbon, oxygen and nitrogen. Titanium bars‍ Which aluminum is the main alloying elements titanium, improving its 

normal temperature and high temperature strength of the alloy, reduce the proportion increased 

elastic modulus have a significant effect. ② stable β-phase, reducing the element of the phase 

transition temperature of β stabilizing element, and can be divided isomorphous and eutectoid type 

two kinds. Application of titanium alloy products, the former molybdenum, niobium, and vanadium; 

latter chromium, manganese, copper, iron, and silicon. ③ small element of the phase transition 

temperature of the neutral elements, zirconium, tin and so on. Oxygen, nitrogen, carbon and hydrogen 

are the main impurities of titanium. Oxygen and nitrogen in the α phase has a greater solubility of 

the titanium alloy has a significant strengthening effect, but the plastic down. Usually provides 

the oxygen and nitrogen content of titanium in the 0.15 to 0.2% and 0.04% to 0.05% or less, 

respectively. The solubility of hydrogen in the α phase is very small, titanium dissolved in excess 

hydride hydrogen will produce the alloy brittle. Titanium is usually controlled hydrogen content of 

0.015% or less. The hydrogen dissolved in the titanium is reversible, can be removed by vacuum 

annealing. Density copper titanium is generally about 4.5g / cm3, only 60% of steel, titanium's 

strength was close to the strength of ordinary steel, some high-strength titanium alloy structural 

strength than a lot of steel. Therefore, titanium strength (strength / density) is much larger than 

other metal structural materials. Copper titanium alloy with high strength and low density, good 

mechanical properties, titanium grade 2 sheet‍ good toughness and corrosion resistance. In addition, the process performance 

titanium poor machining difficulties in thermal processing, it is very easy to absorb nitrogen 

hydroxide carbon and other impurities. There are poor abrasion resistance, complex production 

process. Titanium is mainly used for the production of aircraft engine compressor components, 

followed by the structure rockets, missiles and high-speed aircraft. Light quality titanium and 

titanium alloys, high-strength, yield ratio, non-magnetic, there is biologically inert and has 

excellent corrosion resistance. In marine environments, titanium and titanium alloys almost no 

corrosion, has excellent corrosion resistance in most chemical media. Now, with the advancement of 

technology and the application of new materials industries for increasing the degree of titanium 

valves as a variety of special circumstances and special fluid media delivery system essential 

products have been widely applied. However, different fields and industries fluid medium and 

environmental conditions vary, the titanium material of the valve performance and other requirements 

are different. Meanwhile, due to the requirements of the different components of performance 

titanium valves differences, different molding process as well as reduce the cost of some parts need 

to use alternative materials and other factors, selection as one of technical problems must be the 

primary consideration titanium medical grade titanium alloy‍ valve design manufacture, and by widespread concern and attention.

Pressure casting to reduce machining surgical implant titanium

Titanium and titanium alloy pressure casting

Pressure casting to reduce medical titanium bar‍ machining precision casting, precision casting blank so close to finished product forming method of the most promising, especially as titanium and titanium alloy processing this difficult and expensive metal. Early in the development of titanium alloy precision casting there are people who want to use this method to produce titanium alloy precision castings, but because of the technical level and limited conditions, this idea can not be achieved. After titanium casting research effort of a few years, the former Soviet Union in the titanium grade 2 sheet‍ study of titanium pressure precision casting technology has solved some problems: the vacuum device is built in the press (melting in vacuum chamber and vacuum die casting room); found some possible new heat-resistant material cast member pressure casting and die casting machine; successful research can ensure to superheat and each batch of metal can medical grade titanium alloy‍ be special melting process precise ingredients.

How to measure the melt viscosity titanium plate 

Drums and surface tension of the melt is cast alloy surgical implant titanium‍ melt important physical properties, they are directly related to the melting conditions, but also decided plate fluid flow and an important factor in filling of titanium. 

     Viscosity of titanium former Soviet scholars have conducted a lot of research was, and that the new titanium sheet price‍ structure of the melt, whereas in the binary titanium plate, with the alloy to the transition from a single-phase region multiphase region, the viscosity increases several times. When the melt viscosity was measured using a titanium crucible twist method, the graphite material of the crucible, and the crucible was measured in the elastic medical titanium plate suspension with the gold wire twisting motion. Since the graphite crucible materials contaminate the carbon component alloy, therefore measured viscosity values ​​will be affected, but by comparing different carbon titanium viscosity liquid at different temperatures, and extrapolated to determine the titanium plate viscosity of the melt
