Glasses strong as steel: A fast way to find the best

Scientists at Yale University have devised a dramatically faster way of identifying and characterizing complex alloys known as bulk metallic glasses (BMGs), a versatile type of pliable glass that's stronger than steel.

Using traditional methods, it usually takes a full day to identify a single metal alloy appropriate for making BMGs. The new method allows researchers to screen about 3,000 alloys per day and simultaneously ascertain certain properties, such as melting temperature and malleability.

"Instead of fishing with a single hook, we're throwing a big net," said Jan Schroers, senior author of the research, which was published online April 13 in the journal Nature Materials. "This should dramatically hasten the discovery of BMGs and new uses for them."
