Forming and Simulation of Titanium Alloy Ti-6Al-4V by Hot Isostatic Pressing

Numerical simulation of titanium alloy powder during hot isostatic pressing (HIP) with Shima model is studied in this paper. Material parameters in this model were determined based on uniaxial compression test with different relative density specimens. A titanium alloy ring sample was designed and formed by hot isostatic pressing. The sample was analyzed by using Shima model in the platform of MSC.Marc with the determined parameters of titanium alloy (Ti-6Al-4V). The results of simulation with Shima model were in a good agreement with that result of experiment. Finally, the model is successfully applied to complex model of impeller to predict the deformation during HIP.
