When it comes to metallurgy, it is common knowledge that smaller grains make for harder metals. But how exactly do you achieve these grains? A group of Brown University researchers has found a method for smashing individual metal nanoclusters that leads to metals that are up to four times harder than naturally occurring structures. This new method is quite different from conventional hardening techniques.
