一、序言钼有高的熔点,对液态金属钾、钠、铋及熔盐等的抗蚀性好,抗辐照性能也较好,是反应堆中很有前途的结构材料之一。但由于钼的抗氧化能差、性脆及加工性能差(特别是熔焊性能),这就大大影响了它的应用范围。综合考虑核物理和机械性能后,认为在快中子增殖堆中使用钼比较经济,因此对于钼作为包套材料的研究工作,在国外一直在
First, the preamble Molybdenum has a high melting point, liquid metal potassium, sodium, bismuth and molten salt corrosion resistance is good, anti-radiation performance is better, is one of the very promising structural materials in the reactor. However, due to poor oxidation resistance of molybdenum, brittle and poor processing performance (especially the welding performance), which greatly affected its scope of application. Considering the combination of nuclear physics and mechanical properties, it is considered economical to use molybdenum in fast breeder reactors, and therefore research on molybdenum as a cladding material has been conducted abroad
