| 摘要 |
Metastable beta titanium alloys and methods of processing metastableβ-titanium alloys are disclosed. For example, certain non-limiting embodiments relate to metastableβ-titanium alloys, such as binaryβ-titanium alloys comprising greater than 10 weight percent molybdenum, having tensile strengths of at least 150 ksi and elongations of at least 12 percent. Other non-limiting embodiments relate to methods of processing metastableβ-titanium alloys, and more specifically, methods of processing binaryβ-titanium alloys comprising greater than 10 weight percent molybdenum, wherein the method comprises hot working and direct aging the metastableβ-titanium alloy at a temperature below theβ-transus temperature of the metastableβ-titanium alloy for a time sufficient to formα-phase precipitates in the metastableβ-titanium alloy. Articles of manufacture comprising binaryβ-titanium alloys according to various non-limiting embodiments disclosed herein are also disclosed. |
