摘要： Provided herein are titanium alloys that can achieve a combination of high strength and high toughness or elongation, and a method to produce the alloys. By tolerating iron, oxygen, and other incidental elements and impurities, the alloys enable the use of lower quality scrap as raw materials. The alloys are castable and can form α-phase laths in a basketweave morphology by a commercially feasible heat treatment that does not require hot-working or rapid cooling rates. The alloys comprise, by weight, about 3.0% to about 6.0% aluminum, 0% to about 1.5% tin, about 2.0% to about 4.0% vanadium, about 0.5% to about 4.5% molybdenum, about 1.0% to about 2.5% chromium, about 0.20% to about 0.55% iron, 0% to about 0.35% oxygen, 0% to about 0.007% boron, and 0% to about 0.60% other incidental elements and impurities, the balance of weight percent comprising titanium.
摘要翻译：本文提供了可以实现高强度和高韧性或伸长率的组合的钛合金，以及制造合金的方法。通过耐受铁，氧和其他附带元素和杂质，合金能够使用较低质量的废料作为原料。合金是可浇铸的，并且可以通过不需要热加工或快速冷却速率的商业上可行的热处理来形成基网形态的α相板条。该合金包含约3.0％至约6.0％的铝，0％至约1.5％的锡，约2.0％至约4.0％的钒，约0.5％至约4.5％的钼，约1.0％至约2.5％的铬，约0.20％至约0.55％的铁，0％至约0.35％的氧，0％至约0.007％的硼和0％至约0.60％的其它附加元素和杂质，余量为钛的重量百分比。
