A glass that is stronger and tougher than steel has been developed in the lab in a collaboration between the Lawrence Berkeley National Laboratory and the California Institute of Technology (Cal-Tech), funded by the Department of Energy Office of Science. This glass can bend, if subjected to stress, rather than shatter. The new kind of strong glass material is a microalloy with palladium, a metal with a high “bulk-to-shear” stiffness ratio that counteracts the intrinsic brittleness of glassy materials.
