  • Method for producing alloy particles
    Patent number: 4009233
    Abstract: A method for producing metal and alloy particles from an article thereof wherein the article is first diffused with a source of gas, such as hydrogen, and then subjected to localized heating to melting temperature. Upon localized melting the diffused gas within the article is liberated to produce an atomizing effect upon the melted material. This atomized material is then cooled sufficiently rapidly to form discrete particles which are then collected for further use, such as in powder metallurgy applications.
