ABSTRACT

Shape memory alloys (SMAs) have fascinated researchers for the last few decades in a range of industrial and medical fields due to their intrinsic properties such as large stress output, recoverable strain, excellent damping, and biocompatibility. SMAs exhibit a thermally induced crystalline transformation between a martensitic phase (a low-temperature phase) and an austenitic phase (a high-temperature phase). Upon cooling below the martensitic finish (Mf) temperature, undeformed
