Abstract

High-temperature superconducting (HTS) magnets made from REBCO tapes are extensively developed for use in various applications, notably in nuclear fusion and particle accelerators. In such applications, the REBCO tapes within the magnet face strong magnetic fields, leading to considerable Lorentz force loads. This force can potentially reduce the critical current (I_c) of the tape and even risk the magnet's structural integrity. In this work, high-strength REBCO tapes have being developed by solder-free bonding various alloys with REBCO tapes to enhance the tapes' yield strength. The irreversible tensile stress of modified REBCO tapes, corresponding to 95% I_c retention at 77 K, self-field, has been measured. The results show that our approach significantly increases the irreversible tensile stress of REBCO tapes from 800 MPa to over 1200 MPa.

高强度REBCO胶带

由REBCO带制成的高温超导（HTS）磁体被广泛开发用于各种应用，特别是在核聚变和粒子加速器中。在这种应用中，磁体内的REBCO磁带面临强磁场，导致相当大的洛伦兹力负载。这种力可能会降低磁带的临界电流（Ic），甚至会危及磁铁的结构完整性。通过无焊料结合各种合金，研制了高强度REBCO带，提高了REBCO带的屈服强度。测量了改性REBCO带的不可逆拉伸应力，对应于77 K自场下95%的Ic保留率。结果表明，该方法将REBCO带的不可逆拉伸应力从800 MPa显著提高到1200 MPa以上。
