Memory alloys that spring back into a pre-defined shape are nothing new, but regular bending means they fatigue and fail within a relatively short time-scale. Now, a team of engineers has developed an ...

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 ...

Researchers have developed a novel copper-based alloy that exhibits a special shape memory effect at temperatures as low as -200°C. The work has been published in the journal Communications ...

Engineers have produced an alloy that springs back into shape even after it is bent more than 10 million times. "Memory shape alloys" like this have many potential uses, but present incarnations are ...
