Abstract:

A new technique for the mesaurement of the thermal diffusivity at high temperatures is described. The diffusivity is determined from the time interval separating two radial isotherms in a cylindrical specimen. The observations are made during the transient heating or cooling period, using a sensitive photoelectric pyrometer developed for the purpose. Measurements are reported on Armco iron, Ta, W, TiC, ZrC, HfC, and TaC. Thermal conductivity data were obtained on TiC, TiN, and ZrC, in order to check the previous results and to provide internal standards for testing the new thermal diffusivity technique. Data which disprove the previous literature results are reported on these compounds. Work on the thermal expansion and specific heat of various refractory materials is also described. Author
