Abstract

The invention discloses a high-strength NiW alloy composite baseband with a cube texture and a preparation method thereof. The key points of the technical scheme of the invention are as follows: the composite baseband is formed by compositing an outer layer and a core, wherein the initial material of the outer layer of the composite baseband is a NiW alloy which is obtained by vacuum induction melting and has W atom percentage of 6-7%; the initial material of the core of the composite baseband is a NiW alloy which is obtained by vacuum induction melting and has W atom percentage of 9%. The invention also discloses the preparation method of the high-strength NiW alloy composite baseband with the cube texture. The NiW alloy composite baseband prepared by the preparation method is good in interface bonding and has strong cube texture and high mechanical strength.

Description

technical field

[0001] The invention belongs to the technical field of high-temperature coated superconductor toughened textured metal substrates, and in particular relates to a high-strength cubic textured NiW alloy composite substrate and a preparation method thereof. Background technique

[0002] YBCO coated superconducting material has become the most likely superconducting material for large-scale industrial application due to its high irreversible field, high current-carrying capacity, and low AC loss. Among them, the RABiTS technical route, that is, the rolling-assisted biaxial textured substrate preparation technology is one of the main technical routes for the preparation of YBCO coated superconducting materials, and the textured metal substrate used as a coated conductor is the key to the RABiTS technical route. At present, Ni5W The alloy base strip has been produced industrially, but because it has ferromagnetism in the liquid nitrogen temperature zone and its yie...
