Broad field of application.Although when the atomic percentage conc of W reaches more than 9%, nickel-tungsten alloy base-band shows as in liquid nitrogen temperature
Without ferromagnetism, but when the atomic percentage conc of W reaches more than 9%, it is difficult to obtained strong vertical by traditional base band syntheti c route
Side's texture.In order to study without ferromagnetism texture nickel-base alloy base band, there is a large amount of scholar by adding the alloy such as vanadium, copper in pure nickel
Unit usually obtains nickel-base alloy base band, although the nickel-base alloy of strong cubic texture can be obtained by traditional base band technology of preparing
Base band, but the ferromagnetism of the texture nickel-base alloy base band obtained and mechanical strength cannot meet simultaneously.Therefore, how nothing is prepared
Ferromagnetism, the texture nickel-base alloy base band of high intensity are the huge challenges that toughness textured metal base band faces.
Summary of the invention
