High-entropy alloy powder
High-entropy alloys break with the traditional alloy design paradigm, which typically relies on one or two dominant elements. Instead, they consist of five or more principal elements in equimolar or near‑equimolar proportions, leveraging high-entropy effects, lattice‑distortion effects, diffusion‑hindered effects, and the “cocktail effect” to deliver superior overall performance far beyond that of conventional alloys. The powders are produced via non‑vacuum gas atomization, exhibiting excellent sphericity and controllable oxygen content. They are suitable for laser powder bed fusion (LPBF), laser directed energy deposition (DED), atmospheric/vacuum plasma spraying, and powder metallurgy hot pressing. These materials have already been successfully applied in areas such as hot‑section components of aeroengines, inner‑wall coatings for nuclear reactors, acid‑resistant valves in the chemical industry, and high‑end cutting tools and molds.
