Abstract: A route for preparing the Fe-Ni-Co alloy was studied. The mixed powders was compressed and sintered under nitrogen gas atmosphere. The mixing composition of metal powders was 54 wt%Fe, 29 wt%Ni and 17 wt%Co. A single-action compression was applied together with a double press-double sinter (P2S2) process. Cooling of specimens was performed by quenching in ice water. Apparent density of 92% of the full density could be obtained. The microhardness of prepared alloy was in the range of 110-144 HV. Detail of microstructure compared with the commercial alloy were given.
