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FeCrAl合金在不同温度下的辐照蠕变性能。

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 at different temperatures is discussed.
