Abstract In the work, a specially prepared powder of the model ordered Cu3Au alloy was used to investigate peculiarities of internal processes that take place in the ordered precipitates similarly to those occurring in austenitic reactor steel under irradiation with fast neutrons. It is shown that, unlike the thermal or deformation disordering, in the case of such impact, the dependence of the lattice parameter on the degree of long-range order presents a kink that testifies to the development under irradiation of competitive processes in the defect structure of the studied material.

Cu3Au 中的辐射诱导无序

摘要 在这项工作中，使用一种特殊制备的模型有序Cu3Au合金粉末来研究在快中子辐照下发生在有序沉淀物中的内部过程与奥氏体反应堆钢中发生的过程相似。结果表明，与热无序或变形无序不同，在这种影响的情况下，晶格参数对长程有序程度的依赖性呈现出一种扭结，证明缺陷结构中竞争过程在辐照下的发展所研究的材料。
