Alloys that can return to their original structure after being deformed have a so-called shape memory. This phenomenon and the resulting forces are used in many mechanical actuating systems, for ...

For the first time, ETH Zurich investigators attained a shape memory effect with objects as small as a few nanometers. This technology can be used to create nanoscale machinery and robotic devices.

This atomistic model showing the coexistence of two solid phases of NiTi: austenite (blue), stable at higher temperatures, and martensite (brown), stable at lower temperatures. The martensite region ...
