Abstract

This chapter considers the main features of heat treatment that allows for obtaining dual-phase steels including enrichment of austenite by carbon in the intercritical temperature range and transformations in cooling affected by preexisting austenite–ferrite interfaces. Individual steps of the processing, including formation of austenite phase, its growth, decomposition, and final tempering of ferrite–martensite mixture, are described. The role of heating rate and initial microstructure before cold rolling is highlighted. The phase transformation as a base of manufacturing of as-hot-rolled dual phase is presented.
