Conditions of Sharp Cube Texture Formation in Thin Tapes of Cu-Ni Alloys for Second-Generation High-Temperature Superconductors

摘要

We have studied the formation of sharp cube texture in Cu-Ni alloy tapes with nickel content 10, 20, 30, and 40 at %, manufactured by cold rolling to 98.6-99% and subsequent recrystallization annealing. Optimum regimes of annealing are determined for all these alloys, which allow a sharp cube texture with similar to 95% cubic grains to be obtained.
