Abstract: Systems for cooling a heat-treated metallic part include a plurality of atomization nozzles disposed on a stage and radially disposed about the part to be cooled; and a fluid in fluid communication with the atomization nozzles. The fluid may gas, liquid, or a combination thereof, e.g., water and gas. During use, the atomization nozzles are generally configured to rapidly cool the thicker sections of the part relative to the thinner section since the thicker sections are generally slower to cool. In some embodiments, the stage can be configured to rotate about the part during cooling.
