Deformation Twins in Ni3Nb Single Crystals with DOa Structure

  • Kouji Hagihara (a1), Takayoshi Nakano (a1) and Yukichi Umakoshi (a1)

Abstract

Plastic 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.
