Forming a perfect cubic texture in thin copper–yttrium alloy strips during cold rolling and annealing

The structure of strips produced from the Cu–1 wt % Y binary alloy using cold deformation by rolling to the degree of deformation of ~99%, followed by recrystallization annealing, as well as the process of texture formation in these strips, is studied. The possibility of forming a perfect cubic texture in a thin strip made of a binary yttrium-modified copper-based alloy has been shown in principle, which opens the prospect of the use of this alloy to produce substrates for strip high-temperature superconductors of the second generation. The optimum conditions of annealing have been determined, which make it possible to form a perfect biaxial texture in the Cu–1 wt % Y alloy with a content of cubic grains {001}〈100〉 ± 10° on the surface of the textured strip of over 95%.
