Bye Bye Titanium

Not too long ago, titanium was known as a revolutionary material for its lightness and its use in composites. This time might be over. Researchers from Caltech have produced metals they call "metallic glass" composites. These metals are reported to be twice as tough and elastic as titanium. A 3mm rod of the composite can support a 2 tons truck. The new composites could be used in the making of lighter vehicles and consumer electronics. For more details, please visit www.wired.com
