Investigating the Effects of Addition of Different Copper Amount in Fe-Cu-C by Powder Metallurgy

Powder metallurgy is one of the most used method to produce metal products for its
high machinability and low cost. Fe-Cu-C is one of the most used alloys out there. In the
system, Cu is added to enhance the properties of Fe. However, Cu addition cause swelling
during liquid phase sintering. Fortunately, the addition of C into the system reduces the
swelling. This paper studies the effect of copper to the system, Fe-Cu-C prepared by powder
metallurgy, with different amount of copper wt%. The scope of study includes microstructure,
physical, and mechanical properties of the system with different copper amount i.e. 5%, 10%,
15%, 20% copper wt%.
