Description
Technical field
The present invention relates to a kind of Ti-6Al-4V titanium alloy large size bar working method, belong to the titanium alloy material technical field, be specially the processing technology of the Ti-6Al-4V titanium alloy large size bar of above, high tissue of diameter 200～400mm, length 3000mm and performance requriements, product is mainly used in important use such as Aeronautics and Astronautics.
Background technology
Advantages such as titanium alloy has the specific tenacity height, resistance to corrosion is strong, high-temperature behavior is good, workability is good are the important materials that use in fields such as Aeronautics and Astronautics, weapons.Aircraft industry is the main application fields of titanium alloy, and Ti-6Al-4V (trade mark is TC4 in China's national standard) is the alloy designations of consumption maximum, accounts for about 70% of titanium alloy ultimate production, is mainly used in the structural part of aircraft.Along with the development of aircraft industry, for safe reliability, prolongs life, the raising structure benefit that improves aircraft, the development trend of airplane design is to reduce welding, the employing heavy froging of load spare and large-scale integral forging.For satisfying development, the production of heavy froging and large-scale integral forging, need to use high quality, large-size titanium alloy bar.Yet, in the above bar production method of Ti-6Al-4V titanium alloy Φ 100mm, need adopt upsetting pull repeatedly to forge at home for guaranteeing tissue, performance uniformity and meeting the requirements.And the forged realization of upsetting pull is to rely on artificial clamping complete operation, thereby be subjected to the restriction of upsetting pull forging operation method, make that the cycle of the above bar production of domestic Ti-6Al-4V titanium alloy Φ 100mm is long, the bar substance is less, the quality product consistence is relatively poor, and the UT (Ultrasonic Testing) rank is low.The diameter of rod of suitability for industrialized production and application is Φ 220mm to the maximum at present, and single Zhi Changdu only has about 1.5 meters, is difficult to satisfy the demand in fields such as domestic and international Aeronautics and Astronautics, naval vessel.Though domestic many units have carried out the development of the above scale rod bar of Φ 220mm, but still be confined to little blank upsetting pull forging manufacturing technique repeatedly, bar length is difficult to improve, and tissue, UT (Ultrasonic Testing) and quality conformance etc. require still to exist bigger gap.
Summary of the invention
The technical problem that solves
For fear of the deficiencies in the prior art part, the Ti-6Al-4V titanium alloy large size bar working method that the present invention proposes makes that forging production process realizes mechanized operation, has reduced manually-operated randomness, batch quality conformance height, the production cycle significantly shortens.
Technical scheme
Basic thought of the present invention is: replace the upsetting pull forging repeatedly of little substance blank with ingot casting, forging stock solid forging, choose reasonable heating and forging temperature, coupling is forged parameters such as draught, feed, increase the transverse deformation of metal, control β phase region and the forged reasonable deflection of alpha+beta two-phase region, and adopt suitable high-temperature homogenization to handle, thereby obtain tissue and performance uniformity, UT (Ultrasonic Testing) clutter level height, the Ti-6Al-4V titanium alloy large size bar more than diameter 200～400mm, the length 3000mm.
Ti-6Al-4V titanium alloy large size bar working method of the present invention is characterized in that step is as follows:
Step 1 cogging is forged: adopt gas furnace with 1150 ℃～1200 ℃ of the Ti-6Al-4V titan alloy casting ingot heat tracings of Φ 700～950mm specification, forge 2～3 fire with water pressure engine in the above cogging of beta transus temperature then, 950 ℃ of final forging temperatures, every fire time forging ratio is not less than 1.5, and total forging ratio is not less than 3;
Forge in the middle of the step 2: adopt forging stock temperature that electric furnace heating steps 1 finishes below beta transus temperature 20～50 ℃, use dydraulic forging, forging ratio is 1.5～1.8;
Step 3 homogenizing is handled: adopt electric furnace heating forging stock to make that furnace temperature is above 20 ℃～30 ℃ an of beta transus temperature, insulation 0.5～3h entered tank and carries out water cooling with interior forging stock is come out of the stove from electric furnace at 20 seconds then;
Step 4: the forging stock that step 3 is finished is heated to be below the beta transus temperature 30～50 ℃, adopts water pressure engine alpha+beta two-phase region to forge 3～5 fire, and final forging temperature is not less than 800 ℃, and the total forging ratio of two-phase region is not less than 6.
But direct heating after every fire is forged in the step 4, insulation back continue next fire and forge.
Every fire time forging time is no more than 10～12 minutes in the step 4.
Beneficial effect
The Ti-6Al-4V titanium alloy large size bar working method that the present invention proposes, adopt ingot casting/large-scale forging stock solid forging, compare with existing small dimension blank upsetting pull forging manufacturing technique repeatedly, under the restricted condition of upsetting pull distortion blank aspect ratio, the substance of bar significantly improves, and can stablize to reach more than 3 meters.According to the deformation rule in the stress metal processing, select suitable opening to forge and final forging temperature, the rational Match processing parameter, the restriction metal flows along its length in forging process, promote metal in laterally fully distortion, increase and forge saturating property, improve the practical distortion amount and the deformation uniformity of large scale rod bar, thereby obtain to be out of shape tissue abundant, uniformity, and guarantee the product performance requirement.With existing spillikin base upsetting pull forging manufacturing technique repeatedly relatively, can effectively reduce the nonaffine deformation in the upsetting pull process, and forging defect causes single display signals to exceed standard and tissue odds is even causes clutter to exceed standard, thereby improves the UT (Ultrasonic Testing) level of bar.
Adopt Ti-6Al-4V titanium alloy Φ 200～400mm large scale rod bar that the present invention produced, meet the like product international advanced standard, its technical requirements is as follows:
The horizontal room-temperature mechanical property of bar meets the requirement of following table
