Scientists from the National Institute of Materials Science in Japan have created a highly elastic alloy of titanium and nickel. It can stretch up to 20 times. The researchers developed a three-step procedure that allows the alloy to exhibit its unique properties at different temperatures. In the process, it was first deformed by more than 50%, then heated to 300°C and elongated again by 12%. As
