摘要： A spray forming method for producing a metallic ingot and metallic powder from a metallic source of metal or metal alloy includes: forming one or more streams of metal or alloy from the source, gas atomizing one or more streams of metal or alloy to form one or more sprays of atomized droplets, directing the spray(s) of droplets through a spray nozzle to a rotatable hot body, depositing the droplets to the hot body to form the ingot, controlling the process parameters 1) temperature of metal or alloy, 2) inlet and outlet pressure of the spray nozzle, 3) rotation speed of the hot body, and/or 4) distance between the hot body and the spray(s) of droplets, and collecting the metallic powder having a predefined size distribution. The process parameters are controlled such that the ingot yield is 60-80% and the metallic powder yield is 40-20%, relative to the metallic source.
