WebShape Memory alloys are metals that exhibit the properties of pseudo-elasticity and the Shape Memory Effect. Shape Memory Effect – unique ability of materials to be severely deformed and then return to their original shape through stimulus. Current popular Shape Memory Alloys include NiTi (Nickel Titanium), CuZnAl, and CuAlNi. WebAmong these. materials, shape memory alloys exhibit extremely large, inelastic, recoverable strains (of the order of 10%), resulting from transformation between austenitic and martensitic phases. This. transformation may be induced by a change, either in the applied stress, the temperature, or both. ».
