摘要

我们系统地研究了伽马射线照射引起的碳化钛（TiC）纳米晶体结构组成的变化。实验选取了平均晶粒尺寸约为 40 纳米至 60 纳米、具有立方晶体结构（Fm3 m‾）的样品。利用 X 射线衍射法分析了伽马射线照射后发生的变化。实验结果的理论分析采用了里特维尔德法、舍勒法和威廉森-霍尔法，并对它们进行了比较。此外，还对伽马射线在整个结构中引起的非晶化程度进行了量化。

Comprehensive analysis of gamma irradiation-induced crystallographic transformations in TiC nanoparticles using X-ray diffraction techniques

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

\overline{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.

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
