Abstract
The advantages of dual phase steels in structural applications and automobile industries motivate further studies on the effect of processing parameters on the properties of dual phase steel. Production trials of DP steels were performed using a thin slab caster (TSC). Dual phase steel with the composition (in wt. %) of 0.057 C, 0.277 Si, 1.38 Mn, 0.027 Nb, 0.036 P, 0.63 Cr 0.39 Al was produced in sheet thickness of 3.2 mm. The effects of deformation at inter-critical temperatures (790 and 800°C), coiling temperatures (120, 150 and 180°C) and cooling rate (113~136 °C/Sec) on the final microstructure were investigated. Characterization of the dual phase steels mechanical properties was carried out using hardness, quasi-static tensile test, high strain rate tensile tests, and impact tests. The final mechanical properties were correlated with the different microstructure constituents. The effect of martensite content on deformation and fracture was investigated.
