Metallic Glass Stronger Than Steel

Glass has a lot going for it: it's easy to clean and you can see straight through it. The only problem is that it's fragile and brittle, and that means it breaks easily. That's why researchers have created a new type of glass that is stronger and tougher than steel. In fact, this new type of damage-tolerant glass has actually demonstrated a durability greater than any known material. The new metallic glass is a microalloy that features palladium, a metal with a high "bulk-to-shear" stiffness ratio that counteracts the intrinsic brittleness of glassy materials. Those findings come from experiments conducted at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the California Institute of Technology. More>
