Dual-phase steel is a highly sought-after material for automotive structural components, owing to its unique microstructure consisting primarily of ferrite and martensite. The martensite structure is distributed in the form of islands within the ferrite matrix. This material is characterized by a low yield ratio, a high work hardening index, and an excellent bake hardening value.

Based on martensite, it also contains a certain amount of ferrite and about 8%-12% retained austenite. Utilize the transformation-induced plasticity effect of retained austenite during deformation to obtain higher work hardening performance and elongation level. Compared with high-strength steel of the same strength level, Quench & Partitioning (Q&P) steel has better plasticity and formability.
