WebbShape memory alloys (SMAs) actuators Shape memory alloys are a unique class of alloys that have ability to ‘remember’ their shape and are able to return to that shape even after being bent. At a low temperature, a SMA can be seemingly plastically deformed, but this ‘plastic’ strain can be recovered by increasing the temperature.

WebbBy Clive Barnes. Shape memory alloys (SMAs) are materials that can be deformed at one temperature but when heated or cooled, return to their original shape, i.e. the alloy appears to have a memory. Strains of up to about 10% can be fully recovered. Alloys that exhibit this effect only when heated are said to have a "one-way shape memory". http://eprints.umpo.ac.id/7498/4/BAB%20II.pdf hukum pidana formil dan materil
