Embodiment 1
[0017] The NiW alloy rod with a W atomic percentage of 6% obtained by vacuum induction melting is machined into a through hole to obtain a NiW alloy tube with an outer diameter of 20mm, an inner diameter of 10mm, and a length of 24mm, which is used as the outer layer of the composite ingot , the NiW alloy solid rod with a W atomic percentage of 9% prepared by vacuum induction melting was used as the core layer of the composite billet, with a diameter of 10mm and a length of 24mm, and the core NiW solid alloy rod was inserted into the outer NiW In the alloy tube; the mechanically combined composite billet is subjected to high-temperature hot-rolling treatment, the hot-rolling temperature is 1300 ° C for 10 hours, the deformation of each pass of hot rolling is 15% to 25%, and the total deformation is 70% to 80%. The initial composite ingot before cold rolling with large deformation is obtained; the composite ingot obtained by hot rolling is cold-rolled, the deformation of each pa...
