| Abstract Scope |
In this work, the effect of the processing parameters on the microstructure and mechanical properties was studied to obtain a double-phase steel manufactured by hot rolling from a commercial steel. The chemical composition and the desired mechanical properties were determined by simulation. The steel with the target chemistry was manufactured from the chemical modification of a commercial AISI/SAE 1018 steel by melting in an induction furnace. Chemical analysis was developed by spark emission spectroscopy. The samples subjected to different lamination passes were analyzed by Optical Microscopy -MO- and Scanning Electron Microscopy -SEM-. The experimental results showed that it is possible to obtain a double-phase
steel through controlled rolling. The best combination of microstructure-mechanical properties, 50 and UTS > 1100 MPa, was obtained when the rolled steel in the range (at T>850‘C by controlled cooling rate at 30 Cls). |
