Intermetallic

A team of engineers has created a steel alloy that is much stronger than ordinary steel and is so resilient that it bounces back into shape, even when blasted with a cannon. The researchers believe it could make super-strong armor or help protect space vehicles from micrometeorites.

A material that has the strength and the lightness of titanium alloy and made from an amalgam of steel, aluminum, carbon, manganese, and nickel, has been developed that may see lightweight steel replace aluminum in lightweight, fuel-efficient automobiles and aircraft.
