Intermediate alloy, preparation method therefor, and use thereof

Abstract

The present disclosure provides an intermediate alloy and a preparation method therefor, and use thereof. The preparation method of the intermediate alloy includes the following steps: S1, performing stranding by taking a wire material of a doping element as a core material and taking a base material wire as a peripheral stranding wire to obtain a first stranding wire; S2, performing diffusion welding on the first stranding wire in a vacuum environment or under a protection of an inert atmosphere, so that a metallurgical bonding is formed between the wire material of the doping element and the base material wire, so as to obtain a second stranding wire; and S3, drawing the second stranding wire to obtain an intermediate alloy wire.
