Abstract
Consideration is given to a version of the pulse method of measurement of the thermal diffusivity of spherical samples with the use of laser heating. The method is based on solution of the heat-conduction equation in a spherical coordinate system. The computerized experimental setup used is described. Measurement results for the thermal diffusivity of Zr, Ni, Fe, Al are reported. The measurement error is no more than 5%.
