The unique characteristics of dual-phase steels

May 07, 2015Dual-phase (DP) steels comprise a soft, continuous phase (a mechanically separable or visually identifiable portion of a structure) known as ferrite surrounding islands of a hard phase known as martensite (see Figure 1).. The ferrite phase is mainly pure iron, just like the extra-deep-drawing steel grades used to make automotive fenders; this phase gives this steel grade its high ductility.
