为了确保快堆和聚变堆的安全运行,快堆元件包壳、工艺管、混合堆的第一壁材料,经过高剂量的快中子辐照后,需要保持一定的韧性。为检验国产材料辐照肿胀和力学性能的变化,发展了一种电镜样品尺寸(φ3×0.25mm)的微型圆盘弯曲试验方法。这种微型圆盘样品体积小,辐照温度易于控制,样品辐照后活性较小,利于开展材
In order to ensure the safe operation of the fast reactor and the fusion reactor, the first wall material of the reactor, the process tube and the hybrid reactor needs to maintain a certain toughness after high dose of fast neutron irradiation. In order to test the variation of irradiation swelling and mechanical properties of domestic materials, a micro-disc bending test method of electron microscope sample size (φ3 × 0.25mm) was developed. This miniature disk sample is small, easy to control the irradiation temperature, the sample activity less after irradiation, which is conducive to the development of materials
