摘要： A method and apparatus for cooling heat-treated metallic work pieces, particularly jet engine components that are normally round in shape, have a complex radial cross-section, and are subject to subsequent machining steps, includes a set of concentric air quench delivery tubes for directing a compressed air quench onto specified areas of the work piece for cooling. A first set of tubes is located above the work piece, and a second set of tubes is located below the work piece. The tubes include a multiplicity of bores around their circumference. The air quench tubes are placed in close proximity to the relatively thicker and more massive portion of the work piece, while the thinner and less massive portions are allowed to cool in normal ambient air, thereby cooling the entire part at a substantially uniform rate. Shields placed at specified locations blocks the flow of compressed air and redirect it away from the thin portions of the part.
