MANUFACTURE METHOD OF BIAXIAL TEXTURED SUPPORT PLATE FROM TRIPLE ALLOY ON COPPER-NICKEL BASIS Russian patent published in 2017 - IPC C22F1/08 C22C9/06 

FIELD: metallurgy.

SUBSTANCE: invention relates to the manufacture methods of biaxial textured support plates for epitaxial application on it the buffering and high-temperature superconducting layers for the band high temperature superconductors (HTSC) of the second generation. The manufacturing method of biaxially textured support plate on the copper-nickel basis includes the melting of the triple alloy, forging, cold reverse rolling upto the deformation degree of ≥ 97% and recrystallization annealing at the temperature of ≥ 1000°C, while iron, or vanadium, or chromium is introduced into the alloy on the copper-nickel basis as the alloying element with the following component ratio, at. %: iron ≤ 3 at. %, or vanadium ≤ 1.1 at. %, or chromium ≤ 3 at. %, nickel - 40-45 at. %, copper - the rest.

EFFECT: method allows to increase the strength of the textured support plate from the triple alloy on the copper-nickel basis, while maintaining the non-magnetization and the texturization degree.
