Abstract

The low carbon steels have good ductility that is favorable for forming but their low strength leads to limiting their application to structures. This paper studies on improving strength of low-carbon steel via rolling deformation and dual-phase treatment. The results show that the dual phase treated steel has a combination of superior strength and good ductility. The tensile ultimate strength of dual phase treated steel reaches 740 MPa with fracture elongation of over 15%, while that of the cold rolled steel only reaches 700 MPa with fracture elongation under 3%.
