摘要
Soluble gas is introduced in a melt material which is then atomized and rapidly cooled. The cooling drives the gas from solution, further disintegrating the atomized material to an ultra-fine powder. In one embodiment the atomization and rapid cooling are effected using a gas atomization die. Introduction of the soluble gas may be effected by addition of reactive constituents to the melt, for reactively forming such gas. Finer powders with desirable metallurgical properties are formed using a metallic melt.
