Atomization of the Fe-rich MnNiCoCr high-entropy alloy for spherical powder production
Description & AMAZEMET association
Powder core wire was used in rePowder to create in-situ alloy from elemental blend. High Entropy Alloys (HEAs), with their unique multi-element compositions, are unlocking new possibilities in materials science due to their exceptional mechanical, thermal, and corrosion-resistant properties. The production of spherical HEA powders through advanced atomization methods, such as sonotrode gas atomization, ensures the uniformity and spherical shape essential for additive manufacturing (AM). Recent research utilizing Metal Powder Cored Wire (MPCW) as feedstock has demonstrated the potential to produce high-quality powders with consistent size distributions and solid solution phases, paving the way for improved powder flow, precise dosing, and optimized layer formation in AM applications.

Abstract
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.
