Shear-coupled migration of grain boundaries: the key missing link in the mechanical behavior of small-grained metals?
Grain size reduction is a very efficient way to block dislocation movements and therefore create very strong metals and alloys. Not only grain boundaries are known obstacles for dislocations, but when reaching nanometer dimensions, crystallites usually become dislocation free, which imposes an addit...
