Hot isostatic pressing is a near-net-shape manufacturing process that usually uses a metal
container to encapsulate powders then consolidate them to fully dense compacts. Metal containers
induce the Mises stress to powder compacts due to the rigidity of the container walls. Thus,
anisotropic deformation of powder compacts. This paper investigates the effect of glass container
encapsulation on densification and deformation behaviors of 316L stainless steel powder during hot
isostatic pressing. Finite element results were compared with measured deformed shape of powder
compact after hot isostatic pressing to study the capabilities of glass containers to form near-netshape parts. Glass container showed more homogeneous densification and isotropic deformation of
compacts than conventional metal containers.
