Shape Memory Alloys

Shape memory alloys (SMA) are materials composed of two or more metallic elements that exhibit shape memory effects (SMEs) through thermoelasticity, martensitic transformation, and their inversion. Shape memory alloy is the material with the best shape memory performance among shape memory materials. Memory alloys have a wide range of applications in the field of clinical medicine, such as artificial skeletons, bone fixation and compression devices, dental orthodontics, various types of endovascular stents, embolic devices, heart repair devices, thrombus filters, intervention wires, and surgical sutures. Memory alloys are playing an irreplaceable role in modern medicine. Memory alloys are also closely related to our daily lives.
