The Effect of Strain Rate on the Mechanical Properties of Single Crystal NiAl

  • Published:
MRS Online Proceedings Library Aims and scope

Abstract

In this study, the strain rate sensitivity of single crystal NiAl has been investigated by performing tensile tests as a function of temperature and two strain rates. Three crystallographic orientations, [100], [110], and [111] were studied. The tensile test results investigated include yield strength, work hardening rate and plastic strain to failure. The data are discussed in terms of deformation mechanisms in NiAl.
