Abstract
Hot isostatic pressing process consolidates metal powders to produce filly dense parts with complex geometries. Deformation behavior of compacts during hot isostatic pressing process typically is anisotropic for powders encapsulated in metal containers. Therefore, post-processing processes are required to fabricate the parts with required shape and dimension. This paper reports the effect of glass container encapsulation on deformation and densification behavior of 316 L stainless steel powder and nickel-based superalloy powder during hot isostatic pressing. Finite element calculations from Abaqus - finite element analysis (FEA) were compared with measured deformed shapes of powder compacts. Finally, samples deformed in glass containers were compared with those in metal containers to study the capabilities of glass containers to form near-net-shape parts. Glass containers transmitted all the pressure applied to the compacts and did not induce the Mises stress to the compacts that leads to homogeneous distribution of relative density over the compacts. Glass containers showed more homogeneous densification and uniform deformation of compacts compared to the conventional metal containers.
