Description
Technical Field

Background
The second generation high temperature superconducting material represented by yttrium barium copper oxide is difficult to prepare a growing line strip material due to the ceramic structure, and the epitaxial deposition of a transition layer film and a superconducting layer film on a tough metal substrate is one of the main technical routes for preparing the superconducting strip material. At present, nickel-tungsten alloy is one of the most widely studied base bands, but the high-performance nickel-tungsten alloy base band is difficult to form strong cubic texture by the traditional preparation technology, which also limits the further development of the nickel-tungsten alloy. The alloy systems of copper-nickel alloy, nickel-vanadium and the like can obtain strong cubic texture, but have poor mechanical property or oxidation resistance, and are not suitable for developing high-performance substrate materials, so that the development of a new alloy system for improving the comprehensive performance of the alloy base band is an important direction in the research field of the coating superconducting strip.
