摘要

本文建立了掺钕钇铝石榴石陶瓷在氙急重离子辐照下缺陷形成和潜径迹生成过程的多尺度模型。计算了材料与Xe离子相互作用前后的结构特征，并估计了晶体基体非晶化区域的大小。计算了理论x射线衍射图，并与实验结果进行了比较。计算结果与实验结果在定性和定量上都很吻合，并提出了基于分子动力学建模结果的x射线衍射数据解释方法。

X-ray Diffraction Study and Modeling of Damaged Layers in Y2.5Nd0.5Al5O12 Ceramics after Swift Heavy Xe Ions Irradiation

The paper presents a multiscale modeling of defect formation and latent track generation processes under irradiation of neodymium-doped yttrium-aluminum garnet ceramics with xenon swift heavy ions. The structural characteristics of the material before and after interaction with Xe ions are calculated, and the sizes of the amorphized region of the crystalline matrix are estimated. The theoretical X-ray diffraction pattern is calculated and compared with the experimental one. Good qualitative and quantitative agreement between the calculation results and the experiment is demonstrated, and an interpretation of the X-ray diffraction data is proposed based on the results of molecular dynamics modeling.
