In this work, the effect of C content on the microstructures and tensile behaviors of Nb-V added microalloyed powder metallurgy (PM) steels were investigated. The samples pressed at 700 MPa and sintered at 1450°C temperature in the sintering argon atmosphere for 1 h were produced. Nb-V added PM microalloyed steels with different carbon ratio were analyzed in terms of tensile test. Results indicated that the images of microstructure that as the proportion of the C in the PM samples increases, the volume of the perlite gets increase gradually and 0.35 wt. % C added Nb-V PM steel showed the highest values in yield strength (YS) and ultimate tensile strength (UTS).
