Abstract

With the rapid development of automobile industry, automobile panel material has also gained great attention, the IF steel has got more and more applications in automobile panel production for its excellent deep drawing propertie s, such as, high strain ratio, high extensibility, high yield ratio, etc. In this paper, through the analysis of thermal simulation results and microstructure of IF steel, we studied the influences of microstructure changes on IF steel with different deformation parameters, obtained the influence laws of the deformation parameters on deformation resistanc e of IF steel. So there is a certain directive significance to control the rolling process of IF steel in the actual production of IF steel.
