Abstract
Taking low carbon Si-Mn antomobile used dual phase steel used for automobile as research object, the effects of tempering temperature and tempering time on microstructure and mechanical properties of dual phase steel were studied.The results show that: compared with the tempering time, tempering temperature has great effect on the mechanical properties and microstructure of steel. By proper heat treatment, cold rolled dual phase steel can obtain good strength and ductility combination.
