WebAug 25, 2024 · In this study, we report on the effect of powder oxidation on Charpy impact energy of Ti-6Al-4V parts manufactured using EBM. In addition to oxidation, the effects on impact energy owing to hot isostatic pressing (HIP), specimen orientation, and EBM process defects were also investigated. This research has shown that excessive powder … WebWhat is Toughness – Definition. Toughness is the ability of a material to absorb energy and plastically deform without fracturing. Toughness can also be defined with respect to regions of a stress–strain diagram. (for low-strain rate). Toughness is related to the area under the stress–strain curve. Toughness is the ability of a material ...
