Low carbon steels can be properly heat treated to produce a high strength dual phase structure of ferrite plus martensite. The heat treatment may consist of an intercritical annealing (between A{sub 3} and A{sub 1}) followed by rapid cooling to promote the austenite{r_arrow}martensite transformation. In this paper, mechanical properties of a heat treated dual phase steel were investigated as a function of the martensite volume fraction. The changes promoted by tempering at 100 C, 200 C and 300 C were measured and investigated. Residual stresses introduced by quenching from the intercritical temperature and the changes occurred during the tempering were also measured.
