Embodiment 1
[0027] Process titanium alloy plates with high impact toughness according to the following process, the steps are as follows:
[0028] (1) Forged slab: using sponge titanium as raw material, smelting three times in a vacuum consumable electric arc furnace, adding alloy elements during the smelting process, and controlling the chemical composition content (wt.%) of the slab to Al: 6.8%, Nb: 2.8 %, Zr: 1.8%, Mo: 1.2%, Fe: 0.03%, Si: 0.02%, and the balance is Ti; then start forging at 950°C, the final forging temperature is 800°C, and the forging process is three piers and three pulls , that is, when forging, the pier is thickened three times, and the length is drawn three times, alternately at intervals, and the reduction in the final pass is 60%. The slab is made by forging process, and its metallographic structure is shown in the appendix figure 1 show, from figure 1 It can be seen that the structure is an equiaxed structure, and there are a large number of primary α phases ...

[0034] Process titanium alloy plates with high impact toughness according to the following process, the steps are as follows:
[0035] (1) Forged slab: using sponge titanium as raw material, smelting three times in a vacuum consumable electric arc furnace, adding alloy elements during the smelting process, and controlling the chemical composition content (wt.%) of the slab to Al: 6.8%, Nb: 2.8 %, Zr: 1.8%, Mo: 1.2%, Fe: 0.03%, Si: 0.02%, and the balance is Ti; then start forging at 950°C, the final forging temperature is 800°C, and the forging process is three piers and three pulls , that is, when forging, the pier is thickened three times, and the length is drawn three times, at intervals, and the reduction in the final pass is 60%. Slabs are produced by forging process;
[0036] (2) Slab rolling: Put the slab into a walking gas heating furnace for heating, set the heating temperature at 980°C, and keep it at 980°C for 50 minutes, then remove the titanium alloy slab from the f...
Embodiment 3
[0039] Process titanium alloy plates with high impact toughness according to the following process, the steps are as follows:
[0040] (1) Forged slab: using sponge titanium as raw material, smelting three times in a vacuum consumable electric arc furnace, adding alloy elements during the smelting process, and controlling the chemical composition content (wt.%) of the slab to Al: 6.8%, Nb: 2.8 %, Zr: 1.8%, Mo: 1.2%, Fe: 0.03%, Si: 0.02%, and the balance is Ti; then start forging at 950°C, the final forging temperature is 800°C, and the forging process is three piers and three pulls , The final pass reduction is 60%. Slabs are produced by forging process;
[0041] (2) Slab rolling: Put the slab into a walking gas heating furnace for heating, set the heating temperature at 880°C, and keep it at 880°C for 50 minutes, then remove the titanium alloy slab from the furnace, and remove it with high-pressure water Scale, rolling in two passes on a two-high reversing mill, the rolling...
