Problems solved by technology

Chinese patent CN102825857A (publication date 2012.12.19) discloses a non-magnetic textured Ni-based alloy composite substrate and its preparation method. Since the deformation resistance of the inner and outer layer materials of this layered composite substrate has a certain difference, during the cold rolling process There will be edge cracking, and the cold rolling of long strips needs to apply a certain traction tension, which is easy to cause strip breakage. Therefore, how to continuously mass-produce high-performance long composite base strips has important practical significance

Abstract

The invention discloses a long composite base band prepared from high-performance textured nickel-based alloy and a preparation method of the long composite base band. An initial raw material of the surface layer of the composite base band is Ni-7.8at.%W alloy prepared by adopting vacuum induction melting; the initial raw material of a core layer is Ni-9.8at.%W alloy prepared by adopting vacuum induction melting; all layers are gradually arranged; a Ni-7.8at.%W / Ni-9.8at.%W / Ni-7.8at.%W composite base band is obtained by means of spark plasma pressurized sintering; besides, the invention also discloses the method for preparing the long composite base band prepared from the high-performance textured nickel-based alloy. The base band is free of ferromagnetic property in a liquid nitrogen temperature area and is high in mechanical strength at room temperature, so the base band is suitable for industrial production.

Description

technical field [0001] The invention relates to a high-performance textured nickel-based alloy long composite substrate and a preparation method thereof, belonging to the technical field of industrial production of high-performance textured metal substrates by high-temperature coating superconductors. Background technique [0002] The irreversible field of yttrium-based superconducting materials has good application prospects in superconducting motors, transformers, current limiters, magnets, superconducting energy storage and other strong electric fields. In addition, the application of strong electric fields requires the preparation of long high-temperature superconducting materials. At present, the calender-assisted biaxially textured base tape preparation technology (RABiTS technology) is one of the main technical routes for preparing yttrium-based coated superconducting tapes. RABiTS technology transfers the ductile metal substrate with cubic texture to the YBCO superco...
