Calculations and experimental observations made on cooling rates during splat quenching are presented. Three possible types of cooling behavior are discussed ideal cooling, intermediate cooling, and Newtonian cooling. The effects of splatting-process variables on the cooling rates are described, the most important of these variables being splat thickness and the quality of the thermal contact between the splat and substrate. Splat-cooling rates range typically from 10,000 to above 10 to the 10th power Csec., depending on the actual conditions. Author
