摘要：

HTSC BiSrCaCuO-based wires and tapes have been produced using oxide dispersion hardened Ag alloys as sheath material. The use of such sheath material results in superior mechanical properties. The 0.1 % yield strength R-p0 1 of wires with 50 % HTSC volume fraction exceeds 100 MPa and may reach values up to 150 MPa depending on the respective alloy. The thermal shock resistance also is improved very much. This progress in mechanical properties removes a major obstacle towards application of HTSC in magnet technology. Work concentrating on upscaling of wire production and especially on improving homogeneity is presented. It is shown that filamentization of Bi-2212 wires may lead to improved critical current densities compared to mono filamentary wires.
