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