Plastic Deformation Behavior

ABSTRACTPlastic deformation behavior and substructures in Ni3Nb single crystals were examined focusing on the operative deformation twin systems. Three twinning systems were operative depending on crystal orientation. The twinning behavior was discussed comparing with that in pure hcp metals. Microcracks initiated at the twin intersection. A large number of twin intersections were analyzed and classified into several types.

Plastic deformation behavior of Ni3V with D022 structure was examined using the single crystals containing two dominant variants of three. At [557] loading orientation, {111}1/6<112] twinning is dominantly operative at low temperatures, but {111}1/2<112] slip is activated at high temperatures accompanied by a rapid drop of yield stress.
