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. Shape memory alloys are actually shape memory intermetallics. Alloys are combinations of metal elements that form a solid solution and maybe precipitates (the precipitate can be an intermetallic). Intermetallics are not in solid solution, but instead have directional bonding and an exact … Meer weergeven Do you remember the liquid metal terminator from Terminator 2?
