摘要：

The investigation of Ni-W alloys in the concentration range of solid solubility of tungsten in nickel proved the potential of this metallurgical system for rolling assisted biaxially textured Substrate (RABiTS) tapes of high performance. The cube texture of Ni+5 at.%W vas characterized by a maximum of the deviation frequency at about 4degrees. For this material the beneficial effect of the initial grain size on the final texture quality vas shown. The YBCO (YBa2Cu3O7-delta) type coatings on CeO2 buffer layers carried absolute currents Lip to I - 130 A at 77 K A critical current density of j(c) = 1.2 MA/cm(2) was achieved at 77 K and zero field on tapes up to 20 cm long, (C) 2002 Elsevier Science B.V.
