Effects of Carbon Equivalent on Microstructure and Properties of C-Mn Hot Rolled Dual-phase Steel
Steel Rolling（2011）
Abstract
The hot rolled dual-phase steel taking carton steel as raw material was developed by reduction composition design principle.The effects of carbon equivalent on microstructure and properties of dual-phase steel was analyzed according the chemical change of mix molten.The result shows that the microstructure of DP steel is F+P,the tensile curve is smooth,the original hardening rate is high and the stamping property is well while C_(eq)=0.32%.
