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 ...

Small pieces of the alloy were put through 10 million "shape memory" cycles Engineers have produced an alloy that springs back into shape even after it is bent more than 10 million times. "Memory ...

The magnetic shape memory effect can be used for designing actuators where the element elongates based on the presence of a magnetic field. The elongation can be reversed fully either by the ...

Another Kickstarter, another opportunity for people to get mad at delayed and poorly functioning (if delivered at all) gadgets. This project aims to make airless tires for bikes and scooters using ...

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 ...

NASA engineers have added a new twist to a cutting edge aerospace technology by demonstrating how a new Shape Memory Alloy (SMA) actuator can fold a 300-lb (136 kg) wing section from an F/A-18 Hornet ...

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 ...
