We made the chemical heterogeneity in steel consisting of mostly martensite with retained austenite by applying intercritical annealing prior to full austenitization. It enables simultaneous improvement in strength and ductility, which have been rega

Austenite plays a key role to improve tensile properties of advanced high strength steel (AHSS). In this study, nano-sized austenite particle was produced in as-quenched martensite by using chemically heterogeneous initial microstructure consisting o

We examine the microstructure and tensile properties of the quenching and partitioning (QP a major fraction of austenite exists as Mn-rich islands surrounded by martensite. Starting with uneven Mn distribution prior to the Q&P process enhanced the au
