The purpose is to determine the new effects and regularities for changing the structure and physical properties of structural and functional solid-state materials, layered instrument structures that are promising when used in the conditions of radiation, thermal and mechanical loads of limiting intensity. Research methods are X-ray, electron-optical, optical and photoelectric analysis of structural and physical properties of structural and functional solid-state materials and layered instrument structures. The main scientific and technique results. It is established that irradiation with VUV and an electron beam results in small structure changes in ZnO, CuI, CdS and CdTe materials and does not practically influence on optical transmittance, band gap and output parameters of Al/ZnO:In/Al UV sensors and SE based on CdS/CdTe. Irradiation by hydrogen and He- plasmas results in more significant structure changes in the materials due to higher energies; however, optical properties are changed insignificantly. It is established that the irradiation with H-plasma (0.45 - 0.75 MJ/m2) results in recrystallization processes in a thin surface layer of the tungsten coating: the [100] texture perpendicular to the surface occurs. The preliminary annealed (free of defects and residual stresses) samples with the [100] texture were found to be more resistant to crack formation than the samples with the [110] texture. The reason of the crack formation is the plastic deformation of the surface layers due to twinning; this is intensified by interaction of the twins with hydrogen filled micropores. The technique for preparation of an icosahedral quasicrystalline phase and a crystal-approximant phase in the film samples on the Eurofer steel substrates was worked out; the technique uses dc-magnetron sputtering of the Ti52Zr30Ni18 (at%) target and the subsequent pulse irradiation of the films by hydrogen plasma with a thermal load of 0.6 MJ/m2. The quasicrystalline phase was found to be resistant to the pulse H-plasma irradiation 0.3 MJ/m2.
