Abstract
A process for reducing film boiling by keeping the quenchant pressure above the vapor pressure of the liquid quenchant, and/or using a controlled quenchant renewal to more uniformly cool the surface of part at the initial moment of contact and apparatuses to conduct the pressure and controlled quenchant renewal are disclosed. It is believed that these processes will improve the heat treating of parts with intricate geometries to provide predictable part distortion. The applicability of the method to gun barrels, tubes, round rings, and hollow axles is explained.
