Professor Lindsay Greer - To Bend or to Break? — new views on the hardening of metals

Kipling’s “Iron‒Cold Iron‒is master of them all” captures the familiar importance of metals as structural materials. Yet common metals are not necessarily hard; they can become so when deformed. This phenomenon, strain hardening, was first explained by G. I. Taylor in 1934. Ninety years on from this pioneering work on dislocation theory, we explore the deformation of metals when dislocations do not exist, that is when the metals are non-crystalline. These amorphous metals have record-breaking combinations of properties. They behave very differently from the metals that Taylor studied, but we do find phenomena for which his work (in a dramatically different context) is directly relevant.
