    • 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.
    • 提供了一种用于生产适用于粉末冶金过程的金属粉末的方法。 该方法包括以下步骤:识别限定适用于粉末冶金过程的金属粉末的第一组粉末尺寸特征;获得包含多种非金属颗粒的非金属粉末;选择一部分非金属粉末 具有第二组粉末尺寸特征的颗粒,并且将所选部分的非金属颗粒还原成金属粉末。 通过还原形成的金属粉末具有接近第一组粉末尺寸特征的粉末尺寸特性,并且适用于粉末冶金过程。 该方法优选允许将非金属原料直接还原成具有期望的粉末尺寸特性(例如期望的粒度分布)的粉末,用于粉末冶金过程而不需要任何进一步处理。
