Abstract
The effect of gamma radiation on the structure of nanocrystalline TiN particles was studied. Initially, nanocrystalline TiN particles were exposed to gamma radiation at doses of 50 kGy, 200 kGy, 900 kGy and 3.5 MGy. The crystal structure of non-irradiated and irradiated samples with different doses of gamma rays was studied by X-ray diffraction method. As a result of the determination analysis of the X-ray diffraction spectra by the Rietvield method, the dependence of the lattice parameters on the radiation dose was established. The effect of gamma irradiation on the size of crystallites was determined by the Scherrer equation. The amorphization occurred in nanocrystalline TiN particles was calculated by the method of integration of diffraction peaks. It was determined that 2.5% amorphization occurred in the specified irradiation interval.
