Deformation and fracture characteristics of ferrite/bainite dual-phase steels

The deformation and fracture characteristics of a low carbon Si&ndash;Mn steel with ferrite/bainite dual&ndash;phase structure were investigated by thermo&ndash;mechanical controlled process (TMCP). The results showed that the curves of the instantaneous work&ndash;hardening factor n* value versus true strain &epsilon; are made up with three stages during uniform plastic deformation: n* value is relatively higher at stage I, decreases slowly with &epsilon; in stage II, and then decreases quickly with &epsilon; in stage III. Compared tothe equiaxed ferrite/bainite dual&ndash;phase steel, the quasi&ndash;polygonal ferrite/bainite dual&ndash;phase steel shows higher tensile strength and n*value in the low strain region. The voids or micro&ndash;cracks formed not only at ferrite&ndash;bainite interfaces but also within ferrite grains in the necked region, which can improve the property of resistance to crack propagation by reducing local stress concentration of the crack tips.<br /
