Deformation-transformation mechanisms in NiTi shape memory alloys (SMAs) wires subjected to tension can be investigated using various methods and techniques, often through either isothermal tensile tests or isostress thermal loading. Excluding the R-phase, there are essentially five deformation-transformation processes (elastic deformation, B2⇔ B19’martensitic transformation, martensite reorientation, plastic deformation of martensite, and plastic deformation of austenite) that can be studied under both isothermal and isostress loads.
