Transmission Electron Microscopic Studies of Shape Memory Structures in NiTi Alloys

Abstract

The reverted microstructure of equiatomic NiTi is characterized for several thermal and thermomechanical situations. The generation of dislocations is shown to occur in the martensite as well as the matrix. The debris left after reversion indicates several structures act together to bring about the conditions required for Shape Memory Effect. The nature of this interaction is affected by prior thermal history.
