Abstract

In this study, effect of substitutional alloying elements such as Cu and Ni on tensile properties of dual phase steel is investigated in Fe-0.1%C steels. The steels are subjected to annealing in various temperatures to obtained 20vol.%, 50vol.% and 80 vol.% of martensite after solution treatment at 1273K for 1.8ks. The annealing temperatures were determined using JMatPro 4.1 software. Microstructures of as-quenched samples are full lath martensitic structure and addition of the Ni or Cu increases hardness of martensite. Annealing and water quenching enhance formation of (ferrite + martensite) dual phase structure. The hardness increases with increasing vol.% of martensite, which increases with increasing annealing temperature. Although yield stress and uniform elongation are independent of addition of the elements, tensile stress, total elongation and strength-ductility balance of the dual phase are improved owing to addition of the elements. Increase in work hardening rate owing to addition of substitutional elements is thought to be main factor improving the strength-ductility balance.
