.... By contrast to the Avrami phenomenological approach, the mesoscale (or grain scale) models take the basic physical mechanisms into account, that is, strain hardening and dynamic recovery, nucleation, grain-boundary migration, and the associated softening effects. Their main advantage, however, is to...
