The possibility of using periodic pulsed laser radiation for spectral analysis of the thermal properties of multilayer metallic materials is studied. Pulse and frequency characteristics of samples are found. An expression for the transfer constant of a thermal signal in multilayer materials is obtained. A parametric model is used to determine the thermal conductivity of the interface in a three_layer Mo(1 μm)–W(48 μm)–Mo(1 μm) sample from the amplitude–frequency characteristic measured before and after irradiation by 9_MeV electrons.
Investigated the effect of annealing on the optical properties of metallic films obtained by setting the plasma-focus "PF-4" on glass substrates. The transmission spectra of these films before and after annealing in air at about 900 K for about 10 minutes. Shows the effect of carbon on the optical properties and electrical conductivity of the films.
A method is developed to analyze the state of the interface in a multilayer metallic system; it is based on spectral analysis of a heat_transfer coefficient. A coefficient of correlation is used to find the relation between the spectral characteristics and the thermal conductivity of the interphase interface. The change in the coefficient of correlation induced by 10_MeV electron irradiation of a multilayer W–Mo system is studied.
The irradiation of type EP-838 austenitic stainless steel by electrons in a high-voltage microscope results in decomposition of the solid solution. The decomposition takes place in two stages. The first stage occurs as a spinodal decomposition which tends to form a lattice of rod-like precipitates along the  direction. The second stage is connected with the formation of needle-shaped precipitates oriented along the  direction.
