摘要
The effect of deformation process parameters on microstructure and mechanical properties of as-hot rolled Si-Mn dual-phase steel were studied by controlled rolling and controlled cooling test. It is found that morphology of martensite with high density dislocation and sub-structure has great effect on mechanical properties of the as-hot dual-phase steel. And consequently the different microstructure of as-hot dual-phase steel can be obtained by controlled coiling temperature, cooling rate and finishing rolling temperature.
