Shape memory alloys are exotic materials that can be deformed at room temperature and return to their "remembered," ...

Smart materials are an interesting field that is growing quickly, and shape memory alloys (SMAs) are one such materials that represent one of the most exciting areas. An SMA can experience ...

The secret to how steel hardens and shape-memory alloys snap into place lies in rapid, atomic-scale shifts that scientists have struggled to observe in materials. Now, Cornell researchers are ...

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 ...

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 ...

In this video excerpt from NOVA's "Making Stuff: Smarter", host and New York Times technology columnist David Pogue visits Virginia Tech, where scientists are developing an artificial jellyfish that ...

The unique properties of shape-memory alloys such as nitinol have lent themselves to a variety of applications across numerous industries, including medical devices. These common shape-memory alloys, ...

ALBUQUERQUE, N.M. — Imagine untwisting a finger-size spring, then holding the flame from a lighter underneath the unraveled section. Like magic, it twirls itself into a spring again because the metal ...

The use of shape memory alloys to manufacture implantable medical devices represents a high-growth portion of the medical materials market today. The ability of these specialized alloys to expand or ...

Scientists captured live action details of the phase transitions of shape memory alloys, giving them a better idea how to improve their properties for applications. Known to many as muscle wire or ...

Although an airliner's engines may be quite loud on takeoff, its wings also create a lot of wind noise when it's landing. According to a new study, the latter problem could be addressed with the ...
