The new material - made from nickel, titanium and copper - shatters previous records and is so resilient it could be useful in artificial heart valves, aircraft components or a new generation of solid-state refrigerators.
The key to its remarkable properties is the way it is crystallised. The nickel, titanium and copper atoms are arranged in such a way that they can switch between two different configurations - again and again and again.
Memory alloys are pretty impressive.
