Embodiment 1
[0021] (1) Upward continuous casting: According to Cr: 0.40 wt.%; Zr: 0.05 wt.%; Ti: 0.05wt.%; the balance is copper for copper alloy material batching, and some pure copper is selected from 1 to 2mmd pure copper sheets , Wrap Cu-Cr, Cu-Zr intermediate alloy and pure Ti with pure copper sheet; the remaining pure copper is pure copper sheet or pure copper powder, pure copper block. Put the balance of pure Cu and sufficient dehydrated charcoal into the heating furnace, smelt in the atmosphere, heat to 1200 ℃, and then put the pure copper sheet wrapped with Cu-Cr, Cu-Zr master alloy and pure Ti into the furnace. In the copper liquid, the temperature of the alloy solution in the furnace was controlled at 1140 °C for 3 minutes, and dehydrated charcoal was added twice to further reduce the burning loss of the alloy. Then the upward continuous casting is carried out to prepare the Φ=13 mm alloy rod.

Embodiment 2
[0029] (1) It is basically the same as step (1) of Example 1, the difference is that the temperature is heated to 1250°C, and the holding temperature is 1200°C; the ingredients of the alloy are Cr: 0.40 wt.%; Zr: 0.06 wt.%; Ti: 0.06wt .%; the balance is copper and unavoidable impurities in pure copper materials.
[0030] (2) Cold drawing: cold draw the alloy rod obtained in step (1) to Φ=7 mm, and the cold drawing process is (Φ=13mm-Φ=12 mm-Φ=10 mm-Φ=9 mm -Φ=8 mm-Φ=7 mm), the total deformation of cold drawing is 71%.
[0031] (3) Solid solution: The cold deformed alloy rod obtained in step (2) was placed in a holding furnace for solution treatment, the solution temperature was 950 °C, the treatment time was 1 h, water quenched, and the obtained alloy rod was pickled.
[0032] (4) Cold drawing: cold draw the alloy rod obtained in step (3) to Φ=4.45 mm, and the cold drawing process is (Φ=7mm-Φ=6 mm-Φ=5.5 mm-Φ=5 mm -Φ=4.7 mm-Φ=4.45 mm), the total deformation of cold drawing is ...
Embodiment 3
[0037] (1) Same as step (1) of Example 1, except that the ingredients of the alloy are Cr: 0.50 wt.%; Zr: 0.06 wt.%; Ti: 0.08 wt.%; the balance is copper and cannot be used in pure copper materials Avoid impurities.
[0038] (2) Cold drawing: The alloy rod obtained in step (1) is cold-drawn to Φ=7 mm after 5 passes, and the cold-drawing process is (Φ=13 mm-Φ=12 mm-Φ=10 mm -Φ=9 mm-Φ=8 mm-Φ=7 mm), the total deformation of cold drawing is 71%.
[0039] (3) Solid solution: The cold deformed alloy rod obtained in step (2) was placed in a holding furnace for solution treatment, the solution temperature was 950 °C, the treatment time was 1 h, water quenched, and the obtained alloy rod was pickled.
[0040] (4) Cold drawing: The alloy rod obtained in step (3) is cold drawn 5 times to Φ=4.45 mm, and the cold drawing process is (Φ=7 mm-Φ=6 mm-Φ=5.5 mm- Φ=5 mm-Φ=4.7 mm-Φ=4.45 mm), the total deformation of cold drawing is 59.6%.
[0041] (5) Aging: The alloy rods obtained in step (4) w...
