Abstract

In ferrous powder metallurgy, copper and graphite are used as common alloying elements. Copper melts at low temperature compared to iron and forms liquid which promote interparticle bond formation. However, it also results in compact swelling. To negate this, graphite is used as an additive. This study examines the influence of copper and graphite addition on the densification, dimensional changes, and mechanical properties of iron compacts sintered at 1120°C. These properties have been correlated with the microstructure.
