To meet the increased competition from alternative, non-ferrous materials, a class of new steels is being developed whose mechanical response is enhanced by a transformation-induced plasticity effect. The improved performance has been attributed to the effect of islands of retained austenite in the initial microstructure, which depends on smaller scale phenomena, particularly its transformation into twinned martensite. A numerical model for retained austenite is presented where the effects of the substructures are incorporated and the mesoscale behaviour is accounted for via a three-dimensional analysis of representative phase layouts.
