Abstract

Powder metallurgy has been widely used to make high purity metals and alloys. We applied the powder metallurgy route to the fabrication of the bi-axially textured Ni and Ni-W alloy tapes for YBCO coated conductors. The Ni and Ni-W powder compacts were cold-rolled into tapes. The Ni powder used in this study was 5 μm in size and 99.99% in purity. To densify them, the Ni and Ni-W rods were sintered at 1100°C for 6h in 96% Ar-4% H₂ atmosphere, and cold-rolled into thin tapes of 80-100 μm thickness. Heat-treatment condition for the development of cube texture were established for the tapes. The out-of plane and in-plane texture of the Ni and Ni-W tapes were about 8°. In this paper, we discuss the effect of the processing variables on the texture development of the Ni and Ni-W tapes.
