摘要

采用基于嵌入原子方法的分子动力学方法模拟了具有体心立方晶格结构的Fe基体中包含小尺寸Cu纳米粒子的Fe-Cu二元体系在升温过程中的原子堆积结构变化. 进行了Cu原子均方位移、Cu原子对分布函数和原子的径向密度分布函数的计算，并对纯Cu原子区、Fe-Cu界面区和纯Fe基体区的分区域原子堆积结构进行了分析. 结果表明，Fe基体内Cu团簇的尺寸及其在Fe基体内所能占据区域的大小，对不同温度下的Cu团簇内原子堆积结构及Fe基体的原子堆积结构具有影响. 升温过程中不同尺寸受基体约束Cu团簇对Fe基体结构改变的影响表现出很大差异. 对于Febulk-Cu135体系，基体的应变临近Fe-Cu界面区，同时在团簇中间的基体区域出现大量空位缺陷和应变集中区；对于Febulk-Cu141体系，随温度升高，基体中出现的应变区域表现为小尺寸、数量多向大尺寸、小数量的变化.

Abstract

Nano-size Cu precipitates are the main products of irradiation embrittlement of nuclear reactor pressure vessel steels. Molecular dynamics simulation within the framework of embedded atom method is performed to study atomic packing change in Fe-Cu binary system, where the small Cu clusters are embedded in the crystal body centered cubic (BCC) Fe lattices. As the temperature increases, atomic packing change occurs in the Fe-Cu binary system. The mean square displacement of Cu atom, pair distribution function of the Cu atoms, and the atomic density profile along the radial direction are calculated. The atom packing structures in pure Cu region, Fe-Cu interface region, and pure Fe matrix are analyzed. The simulation results show that the packing structures in the Cu cluster and the Fe matrix are greatly affected by the sizes of these clusters and the volume of the Fe matrix containing these clusters. The structural changes present apparent differences, for the Fe matrixes contain these confined Cu clusters with different atom numbers during heating. As the Fe matrix can only provide small space to accommodate the Cu atoms, packing patterns in many Cu atoms are disordered for the Febulk-Cu135 system. In this binary system, strain region in the Fe matrix is adjacent to the Cu cluster. In the meantime, there are a lot of vacancy defects and strain regions in the matrix. For the Febulk-Cu141 system, although the Cu cluster contains more atoms, the Fe matrix can accommodate Cu atoms in a larger space, and the majority of these Cu atoms are located at the BCC crystal lattices. With increasing the temperature, the changes can be observed that the number of the strain regions decrease, whereas the sizes of some strain regions increase.
