摘要
通过分子动力学方法模拟纳米晶体(1—3nm)的结构.利用模拟的结果,进行了X射线衍射及径向分布函数的模拟计算.结果表明:纳米晶体晶界呈短程有序,界面原子间距分布很宽;随着晶粒尺寸的减小,晶粒的畸变越大。
Abstract This paper presents the molecular dynamics simulations of atomic structures of nanocrystals (1—3nm).The X ray diffraction patterns and the radial distribution functions corresponding to the above nanocrystalline structures were also computed.The results show that the interfacial component exhibits short range order,and the distortion in crystalline component increases with the decrease of grain size.
