TEMPERATURE DIFFUSIVITY AND THERMAL CONDUCTIVITY OF METALS AT HIGH TEMPERATURES,

Abstract

The steady and nonsteady state methods of the determination of thermal diffusivity are reviewed. A new method for measuring the thermal diffusivity of metals at high temperatures is based on the study of temperature waves in a flat specimen. The heating and formation of temperature oscillations are induced by electron bombardment and the temperature is measured at one point using a photocell. (Author)
