液态金属锂铅包层是最具发展潜力的聚变堆包层之一,其首选结构材料为低活化铁素体/马氏体钢,而它与液态锂铅的相容性是聚变堆材料研究领域的关键问题之一。本文介绍中国低活化马氏体钢CLAM在液态金属锂铅回路DRAGON-1热对流工况下的实验情况及500 h 480℃下初步腐蚀实验结果,并与同样工况下316L奥氏体钢腐蚀结果进行了对比分析。结果显示CLAM钢与液态锂铅的相容性优于316L钢。
Liquid metal lithium lead coating is one of the most promising fusion reactor cladding materials. Its preferred structural material is low-activation ferrite / martensitic steel, and its compatibility with liquid lithium lead is a study of fusion reactor materials One of the key issues in the field. In this paper, the experimental results of the CLAM of Chinese low-activation martensitic steel under the condition of DRAGON-1 thermal convection in the liquid metal lithium lead circuit and the preliminary corrosion test results at 480 ℃ for 500 h are introduced. And the corrosion of the 316L austenitic steel The results of a comparative analysis. The results show that CLAM steel and liquid lithium lead compatibility better than 316L steel.
