Abstract Scope Dual-phase steels currently available evolved out of research initiated in the 1970’s. Today, dual phase steels are the primary AHSS products used in vehicle manufacture and will remain as important design materials well into the future. Improvements continue as enhanced dual-phase steels have been produced with finer microstructures, higher strengths, and better overall formability. Currently there are ongoing developments to produce advanced high strength steels (AHSS) with significantly higher strength-ductility combinations than obtainable through conventional dual-phase steel processing. These steels include transformation induced plasticity steels (TRIP), steels processed by quenching and partitioning (Q&P), and others. Many of the alloying and processing approaches for new AHSS products represent extensions of the fundamental principles that led to the development of dual-phase steels. In this presentation, microstructure developments from the early work on dual-phase steels will be reviewed and contrasted to processing and microstructural developments in new AHSS steel grades.
