Electrical and Mechanical Properties of DI-BSCCO Type HT Reinforced With Metallic Sheathes

Comparison of Electromechanical Properties and Lattice Distortions of Different Cuprate High-Temperature Superconductors

“…The critical stress at which a 5% permanent I c degradation occurs in the Bi-2212 wire with a pure Ag matrix and a Ag-0.2wt.%Mg alloy outer sheath is  irr-5% ≈ 150 MPa, which is about 4 times lower than  irr-5% of the SuperPower tape with a Hastelloy substrate. The reinforced Bi-2223 HT-CA tape ruptured at a stress of about 270 MPA, which is in good agreement with the critical stress of  crit =250 MPa that has been reported elsewhere [32]. The non-reinforced Bi-2223 tape has the lowest critical stress and ruptures already at  crit =130 MPa.…”

High field Ic characterizations of commercial HTS conductors

“…The long length availability and high field performance, aided by the lamination reinforcement [25], encouraged development of several prototype magnets such as a 1.03 GHz NMR magnet [26] and a 3 T MRI magnet operated at 20 K by a cryocooler [27]. The new Ni-alloy laminated conductor (HT-XX) has a tensile stress tolerance of over 500 MPa at 77 K [14] and it has become commercially available very recently.…”

Residual Magnetic Field Measurement of BSCCO and YBCO Tapes by a Hall Probe

“…In this experiment we use two different kinds of HTS tapes: BSCCO tape made by SUMITOMO [7] and YBCO tape made by American Superconducting Corp (AMSC) [8]. Table I describes the characteristics of each HTS tape include their dimensions and critical currents.…”
