Abstract

The results of a calculation of the temperature fields in a plane layer of aluminum oxide when it is rapidly heated and melted by the radiation of a CO₂-laser with different flux densities are presented. The calculations are carried out using a new mathematical model of nonstationary radiation-conduction heat transfer. It is shown that the brightness temperature, measured at a wavelength of 0.65 μm, differs from the surface temperature.
