Investigation of Microstructure, Mechanical, and Tribological Behavior of Nano‐Y 2 O 3 , TiO 2 , ZrO 2 ‐Dispersed W–Ni–Nb–Mo–Zr Alloys Fabricated by Spark Plasma Sintering

W–Ni–Nb–Mo–Zr alloys with 1.0 weight% (wt%) Y 2 O 3 (alloy A), TiO 2 (alloy B), ZrO 2 (alloy C) dispersion synthesized by mechanical alloying for 20 h have been subjected to spark plasma sintering at 1150 °C with 65 MPa pressure and 5 min holding time. X‐ray diffraction analysis reveals the occurrence of intermetallics (W 2 Zr, NiNb, Ni 10 Zr 7 , MoNi), which improves the strength of the alloys. Field‐emission scanning electron microscopy analysis shows that the grain size of alloy A is less compared to alloy B and C. Energy‐dispersive spectroscopy reveals the presence of oxides at the matrix interface. Maximum % relative sintered density, ultrahigh hardness, excellent compressive strength, % compressive strain at the maximum compressive load of 99.5%, 20.42 GPa of 2.55 GPa, 9.7%, respectively, have been recorded for alloy A. Maximum texture intensity of 1.5 is recorded for alloy A which supports the superior mechanical properties. The specific wear rate of alloy A is around 2.78 times less compared to alloy C. The crystal structure transformation of ZrO 2 from monoclinic to tetragonal after sintering deteriorates the mechanical properties and wear resistance in alloy C. The article also reports the operative wear mechanism in the studied oxide dispersion‐strengthened alloy.
