Impact of copper and carbon on mechanical properties of iron-carbon-copper alloys for powder metal forging applications

摘要

There was perceived a lack of information regarding higher strength materials for sinter-forging automotive applications. Work, therefore, was undertaken to develop new higher strength materials for sinter-forging automotive applications and to fill this lack of information. Accordingly, a connecting rod that comprises an iron-based powder metal mixture was developed. The mixture comprises between 3.01% and 3.03% by weight of copper, between 0.57% and 0.64% by weight of carbon, between 0.32% and 0.33% by weight of manganese, and about 0.13% by weight of sulfur.
