A collaborative effort by leading Japanese institutions has led to the development of copper-based alloy (Cu-Al-Mn) with a unique “shape memory effect” at a low temperature of -200°C (−328 °F). This ...

Shape memory alloys (SMA) remember their original shape and return to it after being heated. Similar to how a liquid transforms into a gas when boiled, SMAs undergo a phase transformation when heated ...

In order to address the challenges in fabrication NiTiNb ternary alloy structures, researchers from Shandong University (SDU) have proposed an alloy design strategy to prepare NiTiNb shape memory ...

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.

Shape-memory metals, which can revert from one shape to a different one simply by being warmed or otherwise triggered, have been useful in a variety of applications, as actuators that can control the ...
