DP steel microstructure

The microstructure of Dual-Phase (DP) steels contains dispersion of hard martensite islands in a soft ferrite matrix. Hard martensite islands increases the strength and soft ferrite contributes to good formability resulting in low yield ratio (R_p0.2/R_m). In particular, the level of strain hardening is high at the beginning of forming, as a result of which stretch forming properties of DP steels are good.

CP steel microstructure

The microstructure of Complex-Phase (CP) steels contains dispersion of martensite islands in a matrix consisting of ferrite and bainite. Due to the medium hard bainitic matrix of the microstructure, the yield ratio (R_p0.2/R_m) is higher as compared to DP steels. CP steels have better edge ductility and hole expansion ratio as compared to DP steels, and they allow small bending radius.

High final part strength after processing

Whenever AHSS grades are formed and painted, the work hardening and bake hardening can be utilized for high final part strength. Work hardening occurs during forming, and bake hardening takes place at elevated temperatures, for instance during curing step of painting process.
