Atomization of the Fe-rich MnNiCoCr high-entropy alloy for spherical powder production

This paper explores the innovative technology of ultrasonic atomization by employing metal powder-cored wire as a filament to fabricate spherical powders. The method demonstrates a novel approach to generate uniform size distributions of spherical-shaped powders in the range of 30–60 μm, characterized by a homogeneous high-entropy composition. This technique's significance lies in its ability to efficiently produce High Entropy Alloy (HEA) powder, marking a substantial stride toward energy-efficient routes in material fabrication. The implications extend across multiple industrial sectors, promising new way for advanced materials synthesis and manufacturing processes.
