摘要
针对锆合金在反应堆中与高温水发生反应形成氧化膜的过程,设计了研究型实验“锆合金氧化膜微观组织演变相场模拟”,表征了锆合金氧化膜的微观结构,计算了自由能和界面能,建立了晶粒形成及演变的相场模型,最终实现了锆合金氧化膜微观组织演变的可视化。该实验通过Materials Studio和MATLAB两大软件平台进行热力学计算和相场模拟,适用于本科生研究型计算材料学实验教学,有助于培养学生的科研热情与创新意识。
In view of the zirconium alloy react with high temperature water in the reactor form oxidation film process, a research experiment of “the zirconium oxide film phase field simulation of microstructure evolution”was designed, the microstructure of zircaloy oxide film was characterized, the free energy and the interfacial energy was calculated, grain formation and evolution of the phase field model was established, the visualization of microstructure evolution of zirconium alloy oxide film was realized finally. Thermodynamics calculation and phase field simulation were carried out through two software platforms of Materials Studio and MATLAB. This experiment is suitable for the experimental teaching of research-based computational materials science for undergraduates, which helps to cultivate students’ enthusiasm for scientific research and innovation consciousness.
