A phase-field study of the martensitic detwinning in NiTi shape memory alloys under tension or compression

The degree of shape recovery in shape memory alloys is highly associated with their deformation due to martensitic detwinning. In this work, we studied the microstructural evolution of the martensitic variants in NiTi shape memory alloys under applied tension or compression. We first carried out a p...
