ITER的TF、CS和PF线圈系统使用了一套先进的奥氏体不锈钢，这些材料在低温下会受到循环应力的影响。因此，选择了具有高抗拉强度、高延性和4℃抗疲劳性能的高锰奥氏体不锈钢JK2LB作为CS导体。该材料的低温力学性能数据对ITER磁体的设计具有重要意义。本文对JK2LB板及其焊接接头的力学性能进行了研究。
A suite of advanced austenitic stainless steels are used for the ITER TF, CS and PF coil systems.These materials will be exposed to cyclic-stress at cryogenic temperature. Therefore, high manganese austenitic stainless steel JK2LB, which has high tensile strength, high ductility and high resistance to fatigue at 4 K has been chosen for the CS conductor. The cryogenic temperature mechanical property data of this material are very important for the ITER magnet design. This study is focused on mechanical characteristics of JK2LB and its weld joint.
