“…On the surface of S420 steel, Wang et al [102] used laser cladding to prepare CeO 2 -modified Al-based composites and found that the wear mechanisms were mainly microcutting and oxidative wear without the addition of CeO 2 , and abrasive, microcutting, and adhesive wear with the addition of 1.0%, 1.5%, and 2.0% CeO 2 . It was also stated [103] that a small amount of Y 2 O 3 can exhibit diffuse strengthening and ensure a relatively stable friction coefficient. However, excessive additions will weaken the interfacial bonding and lead to a reduction in the strength, plasticity, and toughness of the alloy.…”

Rare earth elements (REEs) doping technology can effectively control the microstructure and improve the quality and performance of materials. This paper summarizes the research progress of REEs in metal additive manufacturing (MAM) in recent years and briefly introduces the effects of REEs on the molten pool fluidity, purified structure, and interfacial bonding between the molten cladding layer and substrate. It focuses on the mechanism of the role of REEs in the refinement and homogenization of microstructures, including grain growth, columnar to equiaxed transition (CET), and elemental segregation. The reasons for the influence of REEs on the homogenization of the structure and elemental segregation are analyzed. The effects of REE type, content, and dimension on hardness and wear resistance are investigated. Finally, tribological applications of REEs in biological and high-temperature environments are summarized, and the impact of REEs-modified alloys is summarized and prospected.

W–Ni–Nb–Mo–Zr alloys with 1.0 weight% (wt%) Y2O3 (alloy A), TiO2 (alloy B), ZrO2 (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 (W2Zr, NiNb, Ni10Zr7, 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 ZrO2 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.
