Advances in density enhancement of powder metallurgy (P/M) powertrain components have been the one-sided focus of developmental efforts of the conversion program in the industry. But as one of the secondary operations, the P/M equivalents attract, among others, the benefit of light-volume machining in comparison with currently applied wrought components. Through a robust approach, an optimized, resulfurized prealloyed material, capable of satisfying the dual requirements of better machinabilty and good fracture toughness without compromising consolidated density, has been powder-forged (P/F). Characterization of the consolidated material for machinability, modulus of elasticity and fracture toughness reveals a prominent potential of the metal powder in the program. Some evaluations of the data were made and further discussed.
