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

Alloys that can return to their original structure after being deformed have a so-called shape memory. This phenomenon and the resulting forces are used in many mechanical actuating systems, for ...

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 ...

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 ...

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 ...

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 ...

Endowed with the power of memory, certain alloys can magically return to their original shape when heated or deformed. However, the repeated back-and-forth between the original and new configuration ...

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 ...

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 ...

Engineers are closing in on a long imagined goal in aviation, wings that can subtly change shape in midair instead of relying ...
