Abstract: The influence of annealing on the microstructure, mechanical and sliding wear characteristics of Ni-based alloys produced by spark plasma sintering (SPS) was investigated. As-sintered alloys had a lamellar-like microstructure consisting of (γ′)-FeNi3 and γ-(NiFe) phases blended together. Lower Co contents (i.e., 30, 35 wt%) led to the formation of poorly bonded coarse γ precipitate islands. Annealed Ni-5Fe-45Co alloy exhibited the most excellent wear performance with the lowest coefficients of friction (0.142 ± 0.05) and wear-rate (0.3 ± 0.02 × 10−4 mm3/Nm). Annealing resulted in alloys with good strength-ductility combinations due to appreciable γ′ precipitation enhancement.
