Butler, C P; Inn, E C.Y.

A brief analysis of the heat conduction boundary value problem is presented in which an infinite, insulated slab is irradiated on one side with an intense source of thermal radiation from a carbon arc. From the solution of this problem a rapid method of measuring the thermal diffusivity of solid materials at elevated temperatures has been developed. Thermal diffusivities of 9 metals have been measured over temperature ranges from ambient to near the melting point. Advantages, limitations and errors of the experimental procedures are discussed. It has been found that for certain metals the thermal diffusivity is a function of not only the temperature but also the prior thermal history of the metal. (auth)
