Abstract

This paper presents predictions of the mechanical response of sintered FGH96 Ni-based superalloy powder compacts at high temperatures, obtained by the analysis of 3D representative volume elements generated by both X-ray tomography and a virtual technique. The response of the material to a multi-axial state of stress/strain for porosities as large as 0.3 is explored, obtaining the yield surfaces and their evolution as well as scaling laws for both elastic and plastic properties. The two modeling approaches are found in good agreement. The sensitivity of the predictions to particle size, inter-particle friction, applied strain rate, and boundary conditions is also examined.
