本研究采用结合反应速率理论和CALPHAD方法的相场模型，三维模拟Zr-Sn合金在热处理和辐照下的微观结构演变，揭示第二相形成及其对辐照剂量的依赖性。
AI 中文摘要
在本工作中，我们研究了Zr-Sn合金在固溶体热处理阶段以及退火合金在反应堆条件下辐照阶段，溶质和空位浓度空间重排的特殊性。为此，我们采用了相场建模，将反应速率理论和CALPHAD方法结合在一个统一的广义方法中。模拟在三维空间中进行，以获取关于体相中溶质和缺陷重排的详细信息。我们讨论了热处理阶段第二相的出现及其在中子辐照下的稳定性。我们分析了辐照剂量对第二相颗粒统计性质的影响。
英文摘要
In this work we study peculiarities of spatial rearrangement of solute and vacancy concentrations in Zr-Sn alloy at stages of both thermal treatment of solid solution and irradiation of annealed alloy under reactor conditions. To this end, we exploit phase field modelling including reaction rate theory and CALPHAD method combined in one generalized approach. Simulations were done in 3D in order to get a detailed information about rearrangement of solutes and defects in a bulk. We discuss the emergence of the secondary phase at the stage of thermal treatment and its stability under neutron irradiation. We analyze an influence of the irradiation dose onto statistical properties of the secondary phase particles.
