Abstract
This study is devoted to numerical modeling and simulation of the process of forming of metal powders by hot isostatic compaction (HIC) for the production of parts in biomechanics. A continuous model based on a visco plastic law is used to describe the process of densification HIP (hot isostatic pressing). The model was implemented in a finite element code developed under the platform FORTRAN POWER STATION. For numerical simulation, we considered a cylindrical die subjected to isostatic pressure and a temperature field. We study variations of different parameters: relative density and radial shrinkage. To validate the numerical model, the results are compared with experimental data.
