The connecting rod is one of the most important parts in automotive engines, transforming the reciprocalmotion of a piston generated by internal combustion into the rotational motion of a crankshaft. Recent advances in highperformance automobile engines demand corresponding technological breakthroughs in the materials for engine parts. Inthe present research, the powder metallurgy (P/M) process was used to replace conventional quenching and/or temperingprocesses for mass production and ultimately for more cost-efficient manufacturing of high strength connecting rods.The development of P/M alloy powder was undertaken not only to achieve the improvement in mechanical properties,but also to enhance the machinability of the P/M processed connecting rods. Specifically MoS2 powders were added aslubricants to non-normalizing Fe-Cr-Mn-V-C alloy powder to improve the post-sintering machinability. The effects ofMoS2 addition on the microstructure, mechanical properties, and machining characteristics were investigated.
