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 ...

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

The basis of the nickel-titanium shape memory alloy (SMA) class is the intermetallic equiatomic binary alloy NiTi. Its moderate solubility range allows its composition to be changed, and also enables ...

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 ...

Shape memory materials, also known as "metal muscles" or "artificial muscles," have the ability to snap back into their original shape after being stretched, squashed, bent, or otherwise deformed. If ...

A German research team has prototyped an extraordinary heating/cooling system that stresses and unloads nickel-titanium "muscle wires" to create heated and cooled air at twice the efficiency of a heat ...

Humanity may be divided on a great many issues, but most would agree that it would be very cool to have airplane wings made of shapeshifting metal. The geometry of those fabulous foils affects ...
