The mixed powders were pressed at various pressures and sintered at 1120 °C in ammonia atmosphere for 30 minutes. The effect of pressure on porosity and tensile strenght; the addition of Cu, C and Mn on the hardness, fracture toughness, and tensile strength were investigated. An increase in compaction pressure caused decrease on porosity amounts, hence resulted in increased tensile strength. Tensile strength also increased with increased amounts of Cu, C and Mn additions. Furthermore, the hardness values of Fe-Cu-Mn-C PM steel specimens increased with the existence of these elements. Fracture toughness values were decreased depending on hardness and tensile strength of the specimens.trinfo:eu-repo/semantics/closedAccessFe-Cu-Mn-CMechanical propertiesMicrostructurePowder metallurgyArticle2233253302-s2.0-37849036292Q2
