Cooling rates in splat cooling

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 104 to above 1010°C/sec, depending on the actual conditions.
