In the present investigation, effect of 1–4% copper addition on the sintering of Fe–P–Ni, Fe–P–Mo and Fe–P–MCM (Transition Metal Carbide Master alloy, Fe–Mo–Cr–Mn–C) was investigated. The phosphorus in the iron powder was 0.45% while other alloying elements i.e. Ni, Mo and MCM were 1 or 2%. MPIF tensile test pieces compacted at 691 MPa pressure were sintered at 1473 K for 1.8 ks in dry hydrogen. The results showed that copper decreased the shrinkage of all the alloy systems and in some cases zero-dimensional change compacts were obtained. Copper addition invariably improved tensile and yield strengths but decreased ductility of the alloys. The results have been discussed on the basis of diffusivities and liquid phase sintering associated with the presence of both copper and phosphorus.
