Nitinol, an unusual alloy that lends shape-memory characteristics to vascular stents and other small-scale products, may someday prove useful in medical devices of much larger size. Following studies ...

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 ...

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 ...

You’ve likely heard of Nitinol wire before, but we suspect the common base knowledge doesn’t go much beyond repeating that it’s a shape-memory alloy. [Bill Hammack], the Engineer Guy, takes us on a ...

“Smart Materials” are materials that change their shape, color, or size in response to an externally applied stimulus. Examples of “external stimuli” include changes in temperature, application of an ...

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 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 ...
