Title
(EN) PROCESS FOR PRODUCING HIGHLY ORIENTED METAL TAPES
(FR) PROCÉDÉ DE PRODUCTION DE BANDES MÉTALLIQUES HAUTEMENT ORIENTÉES
Abstract
(EN)
The present invention is in the field of oriented metal substrates for high temperature superconductor tapes. In particular, the present invention relates to a process for preparing metal tapes with a high degree of cube texture comprising (a) reducing the thickness of the metal tape and (b) heating the metal tape to a temperature above 40 % of its melting point in Kelvin, wherein the number density of cube-oriented grains nee after thickness reduction is at least 1012 m-3.
(FR)
La présente invention concerne le domaine des substrats métalliques orientés pour bandes supraconductrices à haute température. En particulier, la présente invention concerne un procédé de préparation de bandes métalliques avec un degré élevé de texture cubique comprenant (a) la réduction de l'épaisseur de la bande métallique et (b) le chauffage de la bande métallique à une température supérieure à 40 % de son point de fusion en Kelvin, le nombre volumique de grains orientés cube après réduction d'épaisseur étant d'au moins 1012 m-3.
