Near-net-shape forming of 316L stainless steel powder under hot isostatic pressing

Near-net-shape forming of 316L stainless steel powder is investigated under hot isostatic pressing (HIPing). A stainless steel powder compact and an i nsert were encapsulated by a stainless steel container and hot isostaticall y pressed to produce an axisymmetric near-net-shape part. To simulate densi fication and deformation of a powder compact in the container during HIPing , the constitutive model of Abouaf et al., and that of McMeeking and co-wor kers were implemented into a finite element analysis. The thickness effect of the container on densification was also studied for the axisymmetric par t during HIPing. Densification of a three-dimensional asymmetric part durin g HIPing was also investigated by comparing finite element calculations wit h experimental data by Eisen et al.
