摘　　要：为提高用于超导储能磁体的REBCO带材的机械强度,设计了一种高强度REBCO超导带材。将REBCO带材与超级合金共焊制作高强度带材;在77 K下分别测试了超级合金、原始的REBCO带材以及高强度REBCO超导带材的不可逆应力。结果表明,通过与超级合金共焊,能将REBCO带材的95%临界电流水平下的不可逆应力提高约50%。To enhance the mechanical strength of REBCO tapes used in superconducting energy storage magnets,a high-strength REBCO superconducting tape was designed.The REBCO tape was co-welded with a super alloy to fabricate the high-strength tape.The irreversible stress of the super alloy,the original REBCO tape,and the proposed high-strength REBCO su-perconducting tape were tested at 77 K.The results demonstrate that co-welding with the superalloy can increase the irreversible stress of the REBCO tape at 95%of its critical current level by approximately 50%.
