RESEARCH AND DEVELOPMENT WITH RESPECT TO HEAT TRANSFER IN QUENCHING.
Abstract
The determination of heat transfer coefficients of steel and Ag from experiments under controlled conditions and the correlation and generalization of the experimental results are discussed. Samples were heated and quenched under controlled conditions. Thermocouples were used to record the temperatures at several points in the sample on an oscillograph. The galvanometer traces were read out on a specially constructed oscillogram reader. From these cooling curves, surface heat flux and surface temperature were computed as function of time. Numerical techniques developed for this purpose and programmed for a digital computer were employed. Results are reported as heat flux or heat transfer coefficient vs. surface temperature. (Author)
