The Kinetics of Reorientation of Multi-Variants under the Continuous Tensile Stress:Phase-Field Simulation
The kinetics of martensitic variant reorientation as well as the evolutional pathway under the continuous tensile stress in NiMnGa alloys has been investigated by using Phase-field method.The simulated results revealed that the final structures and the pathway of evolutioncan be determined by the different external stress and there existed a critical stress to obtain the single variant.The related kinetics and the mechanism of the structural conversion were proposed to explain the inner physical nature.The pseudo-elasticity related to the structural conversion was also investigated.The mechanism of the motion for interfacial step associated with the nucleation and growth of one variant in another variant at the twin boundary was discussed.
