    • The present disclosure describes methods of heat treating Ti-based alloys and various improvements that can be realized using such heat treatments. In one exemplary implementation, the invention provides a method of forming a metal member that involves forming an alloy into a utile shape and cooling the alloy from a first temperature above a beta transus temperature of the alloy to a second temperature below the beta transus temperature at a cooling rate of no more than about 30° F./minute. If so desired, the alloy my be treated for a period of about 1-12 hours at about 700-1100° F. Titanium alloys treated according to aspects of the invention may have higher tensile strengths and higher fracture toughness than conventional wrought, mill-annealed Ti 64 alloy.
    • 本公开描述了热处理Ti基合金的方法和可以使用这种热处理实现的各种改进。 在一个示例性实施方式中,本发明提供了一种形成金属构件的方法,其包括将合金形成为无形的形状,并将合金从合金的β转变温度以上的第一温度冷却至低于β转子温度的第二温度 冷却速度不超过约30°F /分。 如果需要,我的合金在约700-1100°F下处理约1-12小时。根据本发明的方面处理的钛合金可以具有比常规锻造,轧制的更高的拉伸强度和更高的断裂韧性, 退火Ti 64合金。
