核燃料包壳作为反应堆的核心结构材料,在长期服役过程中会发生辐照蠕变现象,导致材料机械性能降低,严重影响核能安全。因此探讨了不同晶粒尺寸FeCrAl合金的辐照蠕变性能。
As the core structural material of the reactor, the nuclear fuel cladding undergoes irradiation creep during the long-term service process, resulting in a decrease in the mechanical properties of the material and seriously affecting the safety of nuclear energy. Therefore, Irradiation creep properties of FeCrAl alloys with different grain sizes is discussed.
