THERMAL DIFFUSIVITY OF SOLIDS UTILIZING OPTICAL LASER ILLUMINATION.

Abstract

The application of the flash technique for measurement of thermal diffusivity of solid materials at high temperatures is discussed. The use of the technique, it limitations, and particularly the analytical difficulties encountered in considering high temperature radiation losses and specimen diathermancy are reviewed. The design of a high temperature thermal diffusivity apparatus is outlined utilizing a ruby laser pulse source, an indiumantimonide infrared detector system, and a high temperature tantalum furnace.
