Abstract

A method is provided for producing a metal powder suitable for a powder metallurgy process. The method involves steps of identifying a first set of powder size characteristics that define a metal powder suitable for use in a powder metallurgy process, obtaining a non-metallic powder comprising a plurality of non-metallic particles, selecting a fraction of the non-metallic particles having a second set of powder size characteristics, and reducing the selected fraction of non-metallic particles to a metal powder. The metal powder formed by the reduction has powder size characteristics approximating the first set of powder size characteristics and is suitable for use in the powder metallurgy process. The method preferably allows the reduction of a non-metallic feedstock directly to a powder having desired powder size characteristics, such as a desired particle size distribution, for use in a powder metallurgy process without need for any further processing.
