Dual-Phase Steels: The First Family of Advanced High Strength Steels

Dual-Phase steels have been marketed since the early 1990s and are widely used in the sector of automotive and truck construction. They make up the majority of so-called modern or first-generation AHSS (Advanced High Strength Steels). The superior balance between strength, formability and ductility of DP steels comes from their particular composite microstructure, consisting mainly of ferrite and martensite. This article traces first the …
