  • Atomizing nozzle and process
    Patent number: 5228620
    Abstract: High pressure atomizing nozzle includes a high pressure gas manifold having a divergent expansion chamber between a gas inlet and arcuate manifold segment to minimize standing shock wave patterns in the manifold and thereby improve filling of the manifold with high pressure gas for improved melt atomization. The atomizing nozzle is especially useful in atomizing rare earth-transition metal alloys to form fine powder particles wherein a majority of the powder particles exhibit particle sizes having near-optimum magnetic properties.
    Type: Grant
    Filed: June 19, 1992
    Date of Patent: July 20, 1993
    Assignee: Iowa State University Research Foundtion, Inc.
    Inventors: Iver E. Anderson, Richard S. Figliola, Holly M. Molnar
