AbstractIn this work, the effect of Cr content on the microstructures and tensile behaviors of nonalloyed powder metallurgy (PM) steels were investigated. The samples pressed at 700 MPa and sintered at 1400°C temperature in the sintering argon atmosphere for 1 h were produced. Nonalloyed PM microalloyed steels with different Cr ratio were analyzed in terms of tensile test. The microstructure of the PM steels was characterised by optic microscope. Results indicated that 5 wt. % Cr added PM steel showed the highest values in yield strength (YS) and ultimate tensile strength (UTS)
