Abstract —Present investigation deals with the mechanical properties and microstructure of dual phase (DP) steel. Normalizing and intercritical annealing heat treatments were carried out at 900, 750, 770, and 790 ˚C and DP ferrite–martensite steel was obtained. Interaction behavior of both phases has been analyzed through tensile, hardness and impact strength. Comparison of the DP steel with normalized steel has revealed that hardness and tensile strength increases as intercritical temperature increases. Similarly ductility and toughness decreases as the intercritical temperature increases and normalized steel shows better elongation and toughness. The microstructure analysis shows, as the intercritical temperature increases, martensite quantity increases with decrease in ferrite content, which results in improvement in the tensile strength and hardness. The results have shown a decrease in the ductility and toughness as the volume of martensite increases.
