Within this paper, the mechanical, thermal, and electrical reaction of these form memory wires, with diameters starting from 20 to five hundred ?m, will be examined and talked about, with particular target the look on the actuator. The thermo-mechanical properties are already investigated and calculated by a number of approaches. The most typical

The chromium from the stainless steel kinds a thin, adherent passivating oxide layer that provides corrosion resistance by blocking the diffusion of oxygen to the underlying bulk alloy. Approximately 12–thirteen wt% chromium is necessary to impart the necessary corrosion resistance to those alloys.The historical past of these supplies is as old a
