How is shape memory alloy made

WebTraining of a shape memory alloy (SMA) is a process in which the mechanical response is stabilized. Since in real-world applications of an SMA, stress is variable and different from the training stress, in this paper we study NiTi-based SMAs’ response in higher and lower stresses than the training stress. WebThe most widely used shape memory material is an alloy of nickel and titanium called Nitinol. This particular alloy has excellent electrical and mechanical properties, long fatigue life, and high corrosion resistance. As an actuator, it is capable of achieving up to 5% strain and 50 000 psi recovery stress, resulting in ~ 1 J/g of work output.
