What is a shape memory alloy? Shape memory alloys or SMA's are metals that exhibit shape memory properties. The shape memory effect was first discovered in 1932 in a silver-cadmium alloy. It allows ...

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 ...

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 ...

Researchers used an Artificial Intelligence Materials Selection framework (AIMS) to discover a new shape memory alloy. The shape memory alloy showed the highest efficiency during operation achieved ...

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 study led by Tohoku University, Iwate University, The Japan Aerospace Exploration Agency (JAXA), National Astronomical Observation of Japan, Tokyo City University, and Kyoto University developed a ...

Laser powder bed fusion, a 3D-printing technique, offers potential in the manufacturing industry, particularly when fabricating nickel-titanium shape memory alloys with complex geometries. Although ...

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 ...

An advanced tire technology developed by NASA for use on planetary rovers could be coming to a bike lane near you, with startup the Smart Tire Company leveraging the technology to introduce an airless ...

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 ...
