Densification behavior of 316L stainless steel powder under high temperature

Densification behavior of 316L stainless steel powder was investigated during pressureless sintering, sinter forging and hot isostatic pressing. Experimental data were compared with finite element calculations by using the constitutive models of Abouaf and co-workers and of McMeeking and co-workers. Densification of a stainless steel powder compact in a stainless steel container was studied under hot isostatic pressing. Due to the shield effect of the container, inhomogeneous deformation of 316L stainless steel powder compacts was observed in experiment and also predicted by a finite element analysis.
