WebbThe In-Tl shape memory alloy nanowires were successfully prepared by the simple mechanical injection method. In-situ TEM characterization revealed their reversible fct-fcc phase transitions associated with internal {101} twins, providiing promising characteristic to achieve the shape memory effect on the nanoscale.
WebbShape 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". WebbSpecial Issue Information.
