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.

伽马辐射引起的纳米晶氮化钛 (TiN) 颗粒的变化：结构视角

研究了γ辐射对纳米晶TiN颗粒结构的影响。最初，纳米晶 TiN 颗粒暴露于剂量为 50 kGy、200 kGy、900 kGy 和 3.5 MGy 的伽马辐射。采用X射线衍射法研究了未辐照和辐照不同剂量γ射线样品的晶体结构。通过Rietvield法对X射线衍射光谱进行测定分析的结果，确定了晶格参数对辐射剂量的依赖性。伽马辐射对微晶尺寸的影响由谢乐方程确定。通过衍射峰积分的方法计算了纳米晶TiN颗粒中发生的非晶化。确定在指定的照射间隔内发生了2.5％的非晶化。
