锆合金中空位和溶质铜原子对刃型位错的钉扎效果
Pinning Effects of Vacancies and Copper Solute Atoms on Edge Dislocations in Zirconium Alloys
摘要
Abstract
In order to explore the effect of copper on the irradiation resistance of zirconium alloys,the pinning effects of vacancies and substitutional copper solute atoms on edge dislocations was studied in this paper.First,the binding energy results show that a vacancy and surrounding copper solute atom exhibit an attractive force in most regions.The interaction results indicate that the pinning effect of the copper solute atom on the compres-sion layer of edge dislocations is stronger than that of the vacancy.However,when both copper atoms and vacancies are present,the overall pinning force is less than the sum of their individual pinning forces,suggesting that the interaction between the vacancy and the copper solute atom weakens the pinning effect on edge disloca-tions.The conclusions of this paper contribute to a better understanding of the mechanical properties and micro-structural evolution of irradiated zirconium alloys.关键词
