Preparation method of non-magnetic high-strength texture Ni-W alloy baseband

The invention discloses a preparation method of a non-magnetic high-strength texture Ni-W alloy baseband. The preparation method comprises the following steps: acquiring an Ni-9.6 at.% W alloy cast ingot by adopting vacuum induction smelting, carrying out hot forging and hot rolling on the cast ingot, and removing oxide skin positioned on the surface of a hot rolling blank by combining one-pass cold rolling with shot blast treatment; and successfully acquiring the non-magnetic high-strength strong-cube texture hectometre-level Ni-9.6 at.% W alloy baseband by carrying out warm rolling and the cold rolling with a certain deformation amount, introducing stress relief annealing twice in a cold rolling process, longitudinally shearing the cracked edge of a band in the cold rolling process and finally carrying out continuous recrystallizing heat treatment. The preparation method disclosed by the invention lays a good foundation for realizing the industrialized production of second-generation high-temperature superconductors.
