Shape memory alloys (SMAs) provide new insights in biomedical engineering with the unique properties they exhibit, in applications such as cardiovascular stents, guide wires and organ frame retractors ...

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 ...

Additive manufacturing technology is appropriate for fabricating NiTi products, but the control of microstructure, phase transformation, and mechanical property of NiTi alloys is scarce and imperative ...

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 ...

Some metal alloys will "remember" a shape when you heat them to the same temperature they were originally shaped at. So a straight wire made from one of these "shape memory alloys" might change back ...

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 ...

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 ...

A new material that once deformed will automatically return to its original shape when heated has been developed by researchers in the US. While this is not the first such “shape-memory metal”, the ...

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 ...

Imagine a world of shape-shifters. A surgeon inserts a small lump of plastic into an anesthetized patient and, like magic, it expands into a life-saving mesh tube that keeps a formerly clogged artery ...
