Abstract

A pulsed technique for measuring the thermal diffusivity a and thermal conductivity λ of spherical samples with an allowance for the spatial–time energy distribution over the laser-beam cross section is described. The measured temperature dependences а(Т) and λ(Т) for solid and liquid tin near the melting point of samples are presented. The a and λ measurement accuracies are 5 and 15%, respectively.
