The σ-ferrita phase could be obtained in TRIP steels due to the substitution of aluminum to silicon, resulting on a high strength steel with 1 GPa and an elongation of 23%. Furthermore, simulations on ThermoCalc® shown that the niobium is capable of reduce the free carbon and optimize the formation of σ-ferrite in these materials. TRIP alloys containing 5.6% Al and 0.6% Nb were casted to study the influence of thermomechanical processing on microstructure and crystallographic texture (XRD), by symmetrical hot rolling and symmetrical and asymmetrical cold rolling. The conclusion is that the niobium increased the presence of delta-ferrite and symmetrical rolling led to an optimum crystallographic orientation, reaching good mechanical forming and high strength, as previewed.
