AbstractIn this work, the effect of graphite content on the microstructures and tensile behaviors of Mo added powder metallurgy (PM) steels were investigated. The samples pressed at 700 MPa and sintered at 1400°C temperature in the argon atmosphere for 1 h were produced. Mo added PM microalloyed steels with different graphite ratio were analyzed in terms of microstructure and tensile test. Results indicated that as the amount of the graphite in the PM steels increases, the volume fraction of the pearlite increases gradually. Mo aded PM steel contained 0.6 wt. % graphite showed the highest values in yield strength (YS) and ultimate tensile strength (UTS).
