随着原子能工业的发展,特别是原子能动力工程的发展,对結构材料的要求愈来愈高。它們不仅是处于高温下受着机械損伤及化学腐蝕,而且还要經受強輻射的照射。特别是强中子流及Υ輻射可穿透物貭的內层,破坏原子結构,直接改变固体物貭的各种性能;另一方面,輻射还可改变材料的腐蝕速率,引起化学效应及相态变化,間接地使固体物貭的性能发生严重的变化。因此,系统地研究輻射直接或間接引起固体物貭的这些变化,了解輻射“損伤”的过程,对
With the development of atomic energy industry, especially the development of atomic energy engineering, the demand for structural materials is getting higher and higher. Not only are they exposed to mechanical damage and chemical corrosion at high temperatures, they are also exposed to intense radiation. In particular, the strong neutron flux and the inner layer of γ-radiation-penetrating substance 破 destroy the atomic structure and directly change various properties of the solid matter 另. On the other hand, radiation can also change the corrosion rate of the material and cause chemical effects and phases State changes, indirectly, the serious changes in the properties of solid matter 貭. Therefore, systematic study of these changes in radiation that directly or indirectly cause solid matter, to understand the process of radiation “damage”
