Comparative study of Dual-Phase -590 steel on formability at superplastic region and room temperature

A steel alloy DP590 is commonly used for automobile applications because of its outstanding mechanical characteristics. One crucial limitation this forming that it has limited malleability and ductility. In study, we compared the experimental limit diagram (FLD) at RT 800°C using stretching. An experiment with a strain rate 0.01/s carried out samples cut in four different directions (0°,30°,60°& 90°) as seen from rolling direction. Rolling direction specimens have been found to be among stronger samples. FLD can applied method studying temperature differences formability characteristics DP590. Scanning electron microscopy was analysis deformation pattern. Based on these results, shows material become significantly more formable.
