Abstract
The effect of tempering on mechanical properties, microstructure, and fractographic features of a plain carbon dual-phase steel has been studied. The steel has been intercritically annealed at 760°C and 775°C to get different amounts of martensite and then tempered in the range of 200–600°C. The yield strength and tensile strength decreased drastically on tempering, whereas percentage elongation and reduction in the area increased continuously on tempering up to 600°C. Transmission electron microscopy studies reveal that the martensite in the dual-phase steel tempers in a fashion analogous to that of martensite in fully quenched low- or medium-carbon steels.
