Abstract
Shima model and two different kinds of container designs were described. The final geometries of powder metallurgy (PM) preforms were predicted by using finite element method. Several PM Ti-6Al-4V parts were fabricated through a hot isostatic pressing route for comparison with the prediction from the modelling. FEM simulation can be used for shrinkage prediction of powder during HIPing process. The finite element calculations agreed well with the experimental data for shrinkage of the titanium alloy powder under HIPing. The simulation results is helpful to fabricate near-net-shape PM titanium parts.
