| Abstract Scope |
Ultrasonic atomization (UA) is a rapid solidification technique involving fast cooling rates to produce high-quality powders with spherical shapes, fewer impurities, and more uniform size distribution. UA can provide an extremely clean working atmosphere (oxygen < 10 ppm and H2O < 1 ppm) and produce new reactive/non-reactive alloy powders quickly. The final microstructure of the atomized particles is closely linked with the thermal history and cooling rates experienced during the atomization process. In this work, three different bulk metallic glassy (BMG) alloys Vit1, Fe67Mo6Ni3.5Cr3.5P12C5.5B2.5, and Fe66Co15P7.5C5.5Si3B2Mo1 were atomized in an Ar atmosphere and the resultant powders were characterized. The atomized particles showed exceptional sphericity, while the powder output suitable for additive manufacturing reached up to 60%. The Vit1 and Fe67Mo6Ni3.5Cr3.5P12C5.5B2.5 BMG powders remained amorphous below 80 μm fraction. The innovative ultrasonic atomization method appears to be a promising tool for the preparation of BMG powders suitable for AM |
