CFETR中心螺管模型线圈用316LN异型铠甲力学性能研究

Study on the mechanical properties of jacket of CSMC 316LN

改良后的316LN不锈钢因为其在低温下优异的延展性能,被选作为中国聚变工程实验堆(CFETR)中心螺线管(CSMC)的铠甲材料。主要对316LN铠甲材料进行了室温与低温下的力学性能测试,并进行了统计分析。实验结果表明316LN铠甲拥有非常好的拉伸性能。

Modified stainless steel 316LN was set as a candidate material for the China Fusion Engineering Test Reactor （CFETR） Central olenoid Model Coil（CSMC） because of the high strength combined with a good ductility at cryogenic tempera- ture. This paper described the mechanical properties of 316LN jacket at 300K and 4.2K. The results show that the present 316LN jacket has good tensile properties.
