Abstract
The structure of tapes of binary Cu–0.6 wt % V and Cu–1 wt % Y alloys and texturing process of them in the course of cold deformation by rolling to ~99% and subsequent recrystallizing annealing have been studied. The possibility of achieving the perfect cube texture in thin tapes made from binary copper-based alloys with vanadium and yttrium additions has in principle been shown. This opens the prospect of using them as substrates when manufacturing tapes of second-generation high-temperature superconductors. Optimum annealing conditions for the studied alloys have been determined, which have made it possible to produce the perfect biaxial texture with a content of cube {001}〈100〉 ± 10° grains on the surfaces of textured tapes of more than 95%.
