It Looks a Lot Like Glass, but It's Tough as Steel
The moment a crack forms in a piece of glass, it is prone to spread. That’s because although glass is very strong and resistant to deformation, it lacks the toughness that metals like aluminum and steel have. Now, researchers from the
California Institute of Technology
University of California, Berkeley
, report that they have devised
a new type of metallic glass
that is as strong as glass, but as tough as steel — the toughest of all metals.
