Patent number: 10422027Abstract: Metastable beta titanium alloys and methods of processing metastable ?-titanium alloys are disclosed. For example, certain non-limiting embodiments relate to metastable ?-titanium alloys, such as binary ?-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 metastable ?-titanium alloys, and more specifically, methods of processing binary ?-titanium alloys comprising greater than 10 weight percent molybdenum, wherein the method comprises hot working and aging the metastable ?-titanium alloy at a temperature below the ?-transus temperature of the metastable ?-titanium alloy for a time sufficient to form ?-phase precipitates in the metastable ?-titanium alloy. The metastable ?-titanium alloys are not solution heat treated after hot working and prior to aging.Type: GrantFiled: November 10, 2016Date of Patent: September 24, 2019Assignee: ATI PROPERTIES LLCInventors: Brian Marquardt, John Randolph Wood, Howard L.

Patent number: 8512629Abstract: A system for heat treating an alloy steel component includes a first enclosure and a second enclosure opposed to the first enclosure. The first and second enclosures define a chamber around only a portion of the alloy steel component. The system further includes a heating element in the chamber to heat the portion of the alloy steel component. A method for heat treating an alloy steel component includes placing a first enclosure against a first side of the alloy steel component and placing a second enclosure against a second side of the alloy steel component. The method further includes creating a substantially airtight chamber around only a portion of the alloy steel component between the first and second enclosures and heating the portion of the alloy steel component inside the substantially airtight chamber.Type: GrantFiled: January 18, 2010Date of Patent: August 20, 2013Assignee: General Electric CompanyInventors: Jason Robert Parolini, John Randolph Wood
