From Discover Technology:
Engineers have long sought a material with the strength of glass and the toughness of metal. But the two properties are virtually mutually exclusive. Strong, rigid materials tend to be brittle (think glass), while tough ones that resist shattering are often malleable (think copper). Caltech materials scientist Marios Demetriou and colleagues have recently created a glass made from metals that doubles the combined strength and toughness of the best-performing steel, the benchmark alloy for damage tolerance.
