Specific Heats of Metals and Alloys at High Temperatures

Abstract

AFTER some ten years of experience in the investigation of various physical properties of metals at high temperatures, Prof. F. M. Jaeger and his collaborators at Groningen commenced, about fifteen years ago, the much more difficult investigation of the changes which the specific heats of metallic substances undergo at temperatures up to 1,600° C. At that time there were considerable differences in the data published by various experimenters regarding the specific heats of metals and their temperature coefficients at those high temperatures—differences which could not be accounted for entirely by variations in experimental technique, but which seemed to be due, in part at least, to unknown peculiarities of the metals themselves. As a result of the work of Prof. Jaeger, many of these discrepancies have been removed and much valuable information has been obtained concerning the nature of thermal and molecular transformations in the metallic state.
