| Abstract | Martensitic stabilization caused by deformation in a TiNi shape memory alloy was studied. Special attention was paid to the deformed microstructures to identify the cause of martensitic stabilization. Martensitic stabilization was demonstrated by differential scanning calorimetry for the tensioned TiNi shape memory alloy. Transmission electron microscopy revealed that antiphase boundaries were formed because of the fourfold dissociation of 110(B19), super lattice dislocations and were preserved after reverse transformation due to the lattice correspondence. Martensitic stabilization was attributed to dislocations induced by deformation, which reduced the ordering degree of the microstructure, spoiled the reverse path from martensite to parent phase compared with thermoelastic transformation, and imposed resistance on phase transformation through the stress field. |
