Method for improving cubic texture of Ni-W alloy base band with high W content

The invention belongs to the field of metal base bands of high-temperature super conduction coating conductor textures. Trace quantity of Ag element is added into a Ni-W alloy, the damage of an S element of the Ni-W alloy to the cubic texture can be inhibited by the microalloy of the Ag, thereby improving the content of the cubic texture of the Ni-W alloy base band with high W content and obtaining a metal base band with high content of the cubic texture. The method is simple and feasible, and the prepared Ni-W alloy base band has favorable surface quality and sharp cubic texture and can be directly used for extensionally growing transitional layers and superconductive layers; and meanwhile, the Ni-W alloy base band has no (low) magnetism in a liquid nitrogen temperature zone and high mechanical strength, and can meet and further improve the requirement of the YBCO coating conductor performance.
