Abstract
In the past few years, researchers have studied the transformation mechanisms of temperature-induced thermoelastic martensitic in Ti-Ni shape-memory alloy in an energy perspective ignoring some energy boundaries problems. In order to avoid these errors, this study provides a new way to analyze the transformation mechanism from the interatomic stress point of view based on in-situ X-ray diffraction and the rigid body model. The result shows that the shear transformation is induced by the aggregation of lattice distortion stress during cooling. It provides the possibility for Ti-Ni shape-memory alloys to get more accurate control during martensite transformation in engineering.
