The stress-strain curve of the Mg-Sc alloy sheet obtained at -150ºC. The sheet specimen was loaded in tension up to a strain of 3 percent and then unloaded. The alloy sheet shows a superelastic effect. Credit: Yuji Sutou
Mg-Sc alloy shows shape memory properties. This finding raises the potential for development and application of lightweight SMAs across a number of industries, including aerospace. Shape memory alloys (SMAs) show distinctive behaviours such as shape recovery upon heating and have a superelastic effect. They have been used in consumer electronics, housing facilities, personal ornaments, anti-seismic engineering and medical equipment.
Shape memory characteristics were first discovered in an Au-Cd alloy...
