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 ...

Besides superfluous features like touchscreens and internal cameras, basic refrigerator technology hasn't changed much in decades. They still chill your milk by way of chemical refrigerants and ...

May 26, 2008 Researchers at the University of the Basque Country have used ferromagnetic shape memory alloys to develop experimental devices that can position objects with an incredible accuracy of 20 ...

Researchers have made a lighter and potentially cheaper kind of shape-memory alloy: materials that change shape in response to a magnetic field but remember their original shape. The new material, a ...

A new class of materials known as "magnetic shape-memory foams" has been developed. The foam consists of a nickel-manganese-gallium alloy whose structure resembles a piece of Swiss cheese with small ...

The U.S. National Science Foundation (NSF) has recently reported that two research teams have developed a new porous foam of an alloy that changes shape when exposed to a magnetic field. The NSF ...

Materials scientists have long played with “shape memory alloys,” metals that shift between one shape and another when heated or cooled to just the right temperature. But so far, real-world ...

The premartensite phase of shape memory and magnetic shape memory alloys is believed to be a precursor state of the martensite phase with preserved austenite phase symmetry. The thermodynamic ...
