Example Embodiment
[0029] Example 1:
[0030] Using grade 1 sponge titanium, aluminum vanadium 85 and aluminum beans as raw materials, Ti-6Al-4V components (weight percent wt%) are proportioned according to Al 6.2%, V 4.1%, after mixing, they are pressed into electrode blocks, and then the The electrode block is welded into a smelting electrode by plasma welding, and is smelted three times in a vacuum consumable arc melting furnace to form an ingot. The weight percentages of the main alloy elements, oxygen and iron of the titanium alloy tertiary ingot are: Al 6.1%, V 4.2 %, O 0.13%, Fe 0.08%. Use a hydraulic press or an air hammer to open and forge the ingot at 1050-1150°C into a □220mm upsetting and forging billet, and after one fire and one upsetting, it becomes a Φ160mm round bar billet. Then, diameter forging was carried out at 950°C into a square billet of □70mm. After grinding, the billet undergoes secondary heating, the heating temperature is 900 °C, and temperature-controlled rolling i...

[0035] Example 2:
[0036] Using grade 1 sponge titanium, aluminum vanadium 85 and aluminum beans as raw materials, Ti-6Al-4V components (wt%) are proportioned according to Al 6.2%, V 4.5%, and pressed into electrode blocks after mixing, and then The electrode block is welded into a smelting electrode by plasma welding, and is smelted three times in a vacuum consumable arc melting furnace into an ingot. The weight percentages of the main alloy elements, oxygen and iron of the titanium alloy tertiary ingot are: Al 6.3%, V 4.5 %, O 0.15%, Fe 0.10%. Use a hydraulic press or an air hammer to open and forge the ingot at 1050-1150°C into a □220mm upsetting and forging billet, and after two upsetting and drawing, it becomes a Φ160mm round bar billet. Then, diameter forging was carried out at 950°C into a square billet of □70mm. After grinding, the billet undergoes secondary heating, the heating temperature is 890 °C, and temperature-controlled rolling is performed. During the rolli...
