    • Normally solid materials, e.g. metals or metal alloys, are provided as solid particulates, and preferably as fine spherical to almost spherical, as well as fiber-like, particulates, including solid particulates of a metallic glassy structure, by contacting a molten stream of the material (22) which at a temperature within 25 percent of its equilibrium melting point °K has a surface tension of 10 to 2500 dynes/em. and a viscosity of 0.001 to 1 poise, preferably from 10°C to 100°C above its melting point, with a rapidly moving wall of a centrifugally disposed rotating liquid quench fluid (29), e.g. water or an oil, etc, in a manner adapted to disrupt the stream with breaking of the stream into molten globules or particles and to quench rapidly these globules or particles into the solid particulates. The produced solid particulates subsequently are separated from the liquid quench fluid and classified to find utility for example in powder metallurgical applications.
    • 通常固体材料,例如 金属或金属合金作为固体颗粒提供,优选为球形至近似球形,以及纤维状的颗粒,包括金属玻璃状结构的固体颗粒,通过使材料(22)的熔融流接触,其中 在其平衡熔点的25%以内的温度下,DEG具有10至2500达因/厘米的表面张力。 并且离心设置的旋转液体骤冷流体(29)的快速移动的壁的粘度为0.001至1泊,优选高于其熔点10℃至100℃。 水或油等,以适当的方式破坏流,使流破碎成熔融的小球或颗粒,并迅速将这些小球或颗粒骤冷到固体颗粒中。 所产生的固体颗粒随后与液体骤冷流体分离,并被分类以用于例如粉末冶金应用中。
