A new technique for the measurement 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. Measurements are reported on Ta, ZrC, and TiC in the temperature range 1300° to 1650°C. The data are in good agreement with diffusivities calculated from specific heat and steady-state thermal conductivity measurements.
