Abstract
There is provided an apparatus and method for the manufacture of metallic articles. A molten metal stream is disrupted, such as by gas atomization, to form a plurality of molten metal droplets. The molten metal droplets pass through a cooling zone having a length sufficient to allow up to about 30 volume percent of each of the droplets to solidify. A mold then receives and completes solidification of the metal droplets. When under about 30 volume percent of the droplets is solid, the droplets retain liquid characteristics and readily flow within the mold.
