Embodiment 1
[0041] Grind and polish the surface of 99.95% vanadium rods or vanadium plates, and then cold-roll repeatedly, with a cold-rolling speed of 2m / min. A 10mm vanadium plate undergoes 95 consecutive cold-rollings, each time reducing thickness by about 0.1mm, to obtain a thickness of 0.5mm The vanadium plate, after cold rolling and hardening, has a hardness of more than 200Hv, and the vanadium plate is subjected to stress relief annealing in vacuum, with a vacuum degree of 1×10 -4 Pa, temperature 1000°C, time 3 hours, continue cold rolling after annealing, speed 0.5m / min, thinning about 0.05mm each time, 9 consecutive times until processed into a vanadium foil with a thickness of 0.05mm.
[0042] Then put the vanadium foil into acetone for 4 times of 20kHz ultrasonic cleaning, each time for 5min, and replace with fresh acetone each time, then wipe it with ethanol and dry it with cold wind to get the vanadium foil for use.
[0043] Put the vanadium foil in a vacuum of 1×10 -6 ~1×10...
Embodiment 2
[0049] Grind and polish the surface of a copper rod or copper plate with a purity of 99.99%, and then perform cold rolling repeatedly at a cold rolling speed of 5m / min. A copper rod with a diameter of 20mm undergoes 95 consecutive cold rollings with a thickness reduction of about 0.2mm each time to obtain 1mm thick copper plate. After cold rolling and hardening, based on the judgment that the copper plate is difficult to be cold rolled again, the copper plate is annealed in vacuum, and the vacuum degree is 1×10 - 3 Pa, temperature 300°C, time 3 hours. Continue cold rolling after the annealing treatment, the cold rolling speed is 2m / min, the cold rolling is about 0.1mm each time, and the rolling is divided into 8 times until it is processed into a copper foil with a thickness of 0.2mm.
[0050] Then in a vacuum of 1×10 -3 Stress-relief annealing is carried out under the condition of Pa, the temperature is 300°C, and the time is 2h; after cooling, the copper foil is cleaned i...
Embodiment 3
[0055] Grind and polish the surface of a V-4Cr-4Ti alloy plate with a material composition of 99.9%, and then repeatedly perform cold rolling at a speed of 2m / min to reduce the thickness by about 0.1mm each time. After the cold rolling is hardened, the hardness reaches 200Hv Above, the vanadium plate is subjected to stress-relieving annealing treatment in vacuum, and the vacuum degree is 1×10 -4 Pa, temperature 1000°C, time 3 hours, continue cold rolling after annealing treatment, finally repeated cold rolling into 10mm vanadium alloy plate.
[0056] The vanadium alloy plate and the 30μm thick dysprosium foil are laminated alternately, and then in the tungsten steel mold, sealed with a pure iron sheath, the temperature of 1200 ℃ and the pressure of 180MPa are used for hot isostatic diffusion connection, heat preservation and pressure 3 hours.
[0057] Afterwards, the diffusion-bonded clad plate is cold-rolled, and after hardening to 200Hv, the V-4Cr-4Ti clad plate is treated ...
