Shape memory alloys are the special category of alloys which remembers its original structure and return to their original shape upon heating predominantly used shape memory alloy is made of nickel and titanium known as nitinol shape memory alloys market have gained much attention in the recent years due to alloys unique characteristics. Smart materials have been one of the fastest growing materials needed for medical device manufacturing smart materials, according to the. Shape memory alloys a shape memory alloy (sma, smart metal, memory metal, memory alloy, muscle wire, smart alloy) is an alloy that remembers its. Shape memory is a property of select materials that have the ability to remember the shape given during original thermo-mechanical processing allowing the material to revert to that original shape when subjected to heat. Recenr adl'ances in shape memory alloys 159 the standard thennomechanical processing of ni-ti alloys generates a steep hysteresis loop (a greater shape change with a lesser change in temperature), which generally is desirable in. Materials that can remember their shape and switch from one form to another may sound like science fiction, they are actually real and already in use all around us but the alloy used to produce shape memory materials, based on nickel and titanium is expensive some researchers have started looking for cheaper options. Shape memory when a shape memory alloy is in its martensitic form, it is easily deformed to a new shape however, when the alloy is heated through its transformation temperatures, it reverts to austenite and recovers its previous shape with great force.
