<p>Nickel (Ni)-based alloys with three different compositions of Alloy A (Ni₉₀Cr₅Fe₅), Alloy B (Ni₈₅Cr₁₀Fe₅), and Alloy C (Ni₈₀Cr₁₀Fe₁₀) (in wt.%) were synthesized by mechanical alloying (MA) of elemental powder of Nickel (Ni), Chromium (Cr), and iron (Fe). A high-energy planetary ball mill was used for mechanical alloying for 30 h using tungsten carbide-cobalt ball as grinding medium and toluene as the process controlling agent. The powder samples were compacted, and conventional sintering was carried out at 1100 °C for 2 h in an argon gas atmosphere. The microstructure of the milled powders at different periods and the sintered pellets were examined by x-ray diffraction (XRD), optical microscope (OM), and scanning electron microscope (SEM). The flow properties of the milled powders were examined using the angle of repose, tap density, and bulk density of the alloy powders. The density, mechanical properties (hardness and compression strength), wear, and tests were carried out. The density of the sintered samples is about 60% of the theoretical density, so the alloys were porous materials. The milled powder of alloy B shows the best powder flow properties, so both the green density followed by sintered density are higher for Alloy B (sintered density of 5.32 g/cm³, % relative sintered density: 61.63%). Alloy A exhibits minimum %relative density, hardness, and strength among the investigated alloys. The increased addition of Fe in alloy C increases the strength, hardness and wear resistance.</p>
