Abstract:
The quality of the crystallographic texture is analyzed for thin ribbons made of ternary Cu–40% Ni–$Me$ ($Me$ = Nb, Mo, or W) alloys, which are promising materials for epitaxial substrates. Optimal regimes of recrystallization annealing of $\sim$100-$\mu$m-thick ribbons made of these alloys are determined, which provide perfect cubic texture with a fraction of $\{001\}\langle 100\rangle$ grains of more than 96%. The proposed alloys are paramagnetic at operating temperatures of a high-temperature superconductor and less expensive than the nickel ones; therefore, they may be an alternative to the Ni–4.8 at% W alloy, which is most popular in the production of ribbon substrates.
Keywords:
