Hot isostatic pressing (HIP) has become an important powder consolidation process. Despite widespread industrial use, the process itself is not understood. The purpose of this study is to develop an experimental basis for understanding the HIP process for different powder materials and powder shapes/sizes. Four powder materials (titanium, Ti-6Al-4V, nickel and 316 stainless steel) have been HIP'd over a range of temperatures and times to determine the pressure-temperature-time-final density relationships for HIP'ing. The influence of powder shape and size and the degree of interparticle bonding is also being examined. The experimental data are interpreted in terms of models for densification during hot isostatic pressing of metallic powders.
