Abstract
The powder forging (PF) process is used to produce fully dense powder metallurgy (PM) parts for high performance automotive applications. PF connecting rods have been widely accepted in the US, Japan, and other countries due to higher performance and lower manufacturing costs when compared to conventionally forged steel connecting rods [1]. In order to meet and exceed requirements for higher fatigue strength and better machinability of PF connecting rods, a newly developed machinability enhancer, named KSX, was introduced [2]. A comparison study between powder forged materials prepared with 0.3% MnS and with 0.1% KSX additions showed excellent properties in the case of the mix with KSX.
