ABSTRACT:
Cooling of a workpiece is conducted at selected workpiece locations in accordance with predetermined heat flux, at the locations, required to result in a desired workpiece cooling rate for workpiece integrity, microstructure and mechanical properties. A cooling fluid is controlled to follow the workpiece surface according to preselected cooling fluid convective cooling parameters including, but not limited to, cooling fluid direction, mass flow rate, and velocity at the selected locations.
