技术领域 technical field
本发明涉及一种高强度钛铝镍合金板材及其制备方法，属于钛基合金制造领域。 The invention relates to a high-strength titanium-aluminum-nickel alloy plate and a preparation method thereof, belonging to the field of titanium-based alloy manufacturing.
背景技术 Background technique
Ti-6Al-4V是使用最广泛、最成熟的典型的(α+β)两相钛合金，各 国相继研发的历史已近四十年、并有各自的合金牌号。其成份特征为：合 金元素允许波动范围较宽(Al：5.5％-6.75％)，杂质允许含量较高(Fe： 0.3％max、O：0.2％max、H：0.015％max)；从而带来较高的冶金缺陷可 能性、较低的塑性和韧性及较短的使用寿命。为此，以美、英为首的少数 发达国家又在近20年开发了相应的低间隙合金，如美国UNS R56401、 ASTM F468、Grade 23、AMS4930、Ti-64ELI，英国IMI318ELI，法国 TA6VELI等，广泛应用于低温、医疗、舰船及飞行器等重要领域。其成 份特征为：合金元素允许波动范围较窄(Al：5.5％～6.5％)，杂质允许含 量较低(Fe：0.25％max、O：0.13％max、H：0.0125％)；从而带来较小 的冶金缺陷可能性、较高的塑性和韧性、较好的焊接性能及较长的使用寿 命。比Ti-6Al-4V合金的K1C提高近一倍、da/dN降低达一个数量级，现 已应用在先进的战斗机和新一代民机上。例如，美国将Ti-6Al-4V和 Ti-6Al-4V ELI合金应用于F-16战斗机的水平尾翼转轴、波音767的第一 号驾驶舱风档玻璃窗骨架和UH60A“黑鹰”、SH60B“海鹰”、CH53E“超 级种马”等直升机的主旋翼、尾旋翼转动部件。民机波音747的主起落架 用的支撑梁大型模锻件(重1545kg、长6.2m、宽0.95m、投影面积4.06m2)， 自1969年开始生产直到如今仍在供应中。如今，美国第四代战机F22、 F/A-18E/F等的Ti-6Al-4V(Ti-6Al-4V ELI)钛合金应用已经进入采用更大 型整体模锻件的成熟应用阶段，如F22战斗机零件中钛合金占飞机重量的 41％，其中Ti-6Al-4V ELI又占钛合金重量的87.5％。其中F-22后机身整体式隔框(重1590kg、长3.8m、宽1.7m、投影面积5.53m2)是目前世界 上最大的钛合金闭式模锻件。 Ti-6Al-4V is the most widely used and mature typical (α+β) two-phase titanium alloy. The history of research and development in various countries has been nearly 40 years, and it has its own alloy grade. Its composition characteristics are: the allowable fluctuation range of alloying elements is wide (Al: 5.5%-6.75%), and the allowable content of impurities is relatively high (Fe: 0.3%max, O: 0.2%max, H: 0.015%max); This results in a higher likelihood of metallurgical defects, lower ductility and toughness, and a shorter service life. For this reason, a small number of developed countries led by the United States and the United Kingdom have developed corresponding low-interstitial alloys in the past 20 years, such as the United States UNS R56401, ASTM F468, Grade 23, AMS4930, Ti-64ELI, the United Kingdom IMI318ELI, France TA6VELI, etc., widely It is used in important fields such as low temperature, medical treatment, ships and aircrafts. Its composition characteristics are: the allowable fluctuation range of alloying elements is narrow (Al: 5.5% ~ 6.5%), and the allowable content of impurities is low (Fe: 0.25%max, O: 0.13%max, H: 0.0125%); The possibility of smaller metallurgical defects, higher plasticity and toughness, better welding performance and longer service life. Compared with Ti-6Al-4V alloy, K1C is nearly doubled, and da/dN is reduced by an order of magnitude. It has been applied to advanced fighter jets and new generation civil aircraft. For example, the United States applies Ti-6Al-4V and Ti-6Al-4V ELI alloys to the horizontal tail shaft of the F-16 fighter jet, the No. Main rotor and tail rotor rotating parts of helicopters such as "Sea Eagle" and CH53E "Super Stallion". The large-scale die forgings for the support beam of the main landing gear of the civil aircraft Boeing 747 (weight 1545kg, length 6.2m, width 0.95m, projected area 4.06m2) have been produced since 1969 and are still in supply today. Today, the Ti-6Al-4V (Ti-6Al-4V ELI) titanium alloy application of the fourth-generation fighter jets F22, F/A-18E/F, etc. in the United States has entered the mature application stage of using larger integral die forgings, such as F22 Titanium alloys in fighter jet parts account for 41% of the weight of the aircraft, of which Ti-6Al-4V ELI accounts for 87.5% of the weight of titanium alloys. Among them, the F-22 rear fuselage integral bulkhead (weight 1590kg, length 3.8m, width 1.7m, projected area 5.53m2) is currently the largest closed die forging of titanium alloy in the world.
