Effect of 2 MeV electron beam at the current density 0.09 nA/cm² on surface structure, nanocrystallite size of (ZrTi)CN nanocomposite coating on steel was investigated at Scanning Electron and Atomic Force microscopes, and also X-ray diffractometer. Using the Rietveld method, two structure phases were indentified in the pristine samples: (ZrTi)(CN)-cubic (space group Fm-3m) and TiC — trigonal (sp.gr.R-3m). Electron beam irradiation to the fluency of 4.1 × 1017 electron/cm² resulted in the phase transition of TiC from trigonal (sp.gr.R-3m) to cubic structure (sp.gr.Fm-3m). Besides, nanocrystallite size and shape have changed after the fluency 2.3 × 1017 electron/cm². The lattice parameters have increased up to 3.1 × 1017 electron/cm² fluence and the nanorcrystallite size of nanocomposite was enlarged 26%, which was attributed to generation of defects.

电子束辐照(ZrTi)CN纳米复合材料的表面结构、纳米晶和缺陷

在扫描电子和原子力显微镜以及X射线衍射仪上研究了电流密度为0.09 nA/cm ^{2的2 MeV电子束对钢上(ZrTi)CN纳米复合涂层的表面结构、纳米微晶尺寸的影响。}使用 Rietveld 方法，在原始样品中识别出两个结构相：(ZrTi)(CN)-立方（空间群 Fm-3m）和 TiC-三角（sp.gr.R-3m）。电子束辐照的流畅度4.1 × 1017电子/厘米²导致 TiC 从三角 (sp.gr.R-3m) 到立方结构 (sp.gr.Fm-3m) 的相变。此外，纳米晶尺寸和形状在流利后发生了变化2.3 × 1017电子/cm ² . 晶格参数增加到3.1 × 1017电子/cm ²能量密度和纳米复合材料的纳米微晶尺寸增大了26%，这归因于缺陷的产生。
