A multiscale material model for metallic powder compaction during hot isostatic pressing

Elguezabal Lazcano, Borja (Elsevier, 2023)

The prediction of the distortions during Near-Net-Shape Hot Isostatic Pressing (NNS-HIP) is an intrinsic multiscale problem where the local interactions among particles determine the macroscopic distortions taking place ...
Study of Astroloy powder compaction at high temperature under hydrostatic load using finite elements

Elguezabal Lazcano, Borja (Elsevier, 2021)

The results of existing constitutive models describing the behaviour of metal powder during compaction processes are very different. This reveals the high sensitivity of the mechanical behaviour of porous materials to the ...
