Titanium How hot isostatic processing techniques tube 

    Titanium tube hot isostatic pressing (HIP) is a newly grade 1 titanium sheet‍ developed powder metallurgy processing methods, has been widely used titanium alloy tube casting process, especially in aviation precision castings, titanium tube processing to improve internal casting metallurgical defects to improve the mechanical properties and stability of the casting. 

     Hot isostatic pressing is a titanium alloy tube creep, diffusion process. The treatment temperature is generally (0.6 and 0.9) Ts, where Ts is the absolute temperature of the alloy solidus value. Titanium alloy to be treated is higher than the working pressure in the pipe yield strength and high temperature creep strength of the alloy capable of plastic flow when processing, so that the porosity, porosity defects closed up by a titanium spring wire‍ process requires a longer time or 2h to complete. Typical titanium tube hot isostatic pressing process temperature, pressure force and the time of change.
