Description of Spherical FeCoNiCrCu HEA Powder
Princeton Powder supplies spherical FeCoNiCrCu High-Entropy Alloy (HEA) powder and a wide range of other high-performance multi-principal element alloys designed for additive manufacturing, including 3D printing, rapid prototyping, and powder metallurgy. Our HEA products are available in various forms such as gas-atomized powders, spherical metal powders, ingots, thin foils, and films.
These high entropy alloys, typically composed of five or more metals in near-equimolar ratios, exhibit superior mechanical strength, thermal stability, and corrosion resistance for demanding applications in aerospace, energy, and tooling. Princeton’s free-flowing HEA powders feature tightly controlled particle size distributions, uniform morphology, and are engineered to be agglomerate-free with ultra-low oxygen and carbon content. These properties ensure consistent microstructure and allow the fabrication of large, complex components without compromising material integrity.

Exceptional thermal stability of nanostructured FeCoNiCrCu high entropy alloy facilitated by unusual grain boundary segregation
Abstract: Nanocrystalline metals often suffer from grain coarsening at elevated temperatures, which deteriorates their mechanical properties. One important strategy to retard grain growth is solute segregation at grain boundaries, which can reduce excess Gibbs free energy of grain boundaries and thus impede their motion. The strategy has been widely utilized in binary and ternary alloy systems to stabilize their nanostructures. In present work, we report superior thermal stability of nanostructured FeCoNiCrCu high entropy alloy film prepared by ion beam deposition.
