Alterations in the structural composition of titanium carbide (TiC) nanocrystals induced by gamma radiation exposure were systematically investigated. A sample with an average grain size of approximately from 40 nm to 60 nm and possessing a cubic crystal structure (Fm3 m‾) was selected for the experiment. The X-ray diffraction method has been employed to analyze the changes that occurred after gamma radiation. The experimental results were theoretically analyzed employing the Rietveld, Scherrer, and Williamson-Hall methods, with subsequent comparisons conducted among them. Furthermore, the degree of amorphization induced by gamma radiation throughout the structure was quantified.

使用 X 射线衍射技术全面分析 TiC 纳米颗粒中 γ 辐照诱导的晶体学转变


系统研究了伽马辐射暴露诱导的碳化钛 （TiC） 纳米晶体结构组成的改变。选择平均晶粒尺寸约为 40 nm 至 60 nm 且具有立方晶体结构 （Fm3 m ̅） 的样品进行实验。X 射线衍射方法已被用于分析伽马辐射后发生的变化。采用 Rietveld、Scherrer 和 Williamson-Hall 方法对实验结果进行理论分析，随后对它们进行了比较。此外，量化了整个结构中由 γ 辐射诱导的非晶化程度。
