Abstract : 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 C/sec., depending on the actual conditions. (Author)
