摘要：

An investigation of the stress-induced martensitic transformation produced during deformation in the Ti-Ni shape memory alloy has been made. The results show that the stress-induced martensitic transformation occurs near the crack-tip and this kind of transformation is reversible. Electron diffraction analysis reveals that there is a transitional R-phase that forms during the transformation from the parent phase (B-2) to the martensitic phase (B-19), accompanying a rhombohedral lattice distortion of the alloy.
