Abstract
A method of producing a beta-titanium alloy elongated product form having a chemical composition as specified in UNS R58150 or ASTM F2066-13. The method comprises solution treating, aging, straightening, stress-relief aging, and cooling the elongated product form. Articles of manufacture comprising or produced from beta-titanium alloy elongated product forms made according to the method also are disclosed.

A method of producing a straightened beta-titanium alloy elongated product form, the method comprising:
- solution treating a beta-titanium alloy product form having a chemical composition as specified in UNS R58150 or ASTM F2066-13;
- aging the solution treated beta-titanium alloy product form in a first temperature range of 482° C. to 510° C.;
- applying a stress to the solution treated and aged beta-titanium alloy product form in a second temperature range of ambient temperature to 482° C. for a time sufficient to improve straightness of the solution treated and aged beta-titanium alloy product form, to provide a straightened solution treated and aged beta-titanium alloy elongated product form, wherein the straightened solution treated and aged beta-titanium alloy elongated product form deviates from straight by no greater than 0.0625 inch (1.588 mm) over any 5 foot length (152.4 cm);
- stress-relief aging the straightened solution treated and aged beta-titanium alloy elongated product form in a third temperature range of 426° C. to 510° C., to provide a stress-relief aged straightened beta-titanium alloy elongated product form;
- and
- air cooling the stress-relief aged straightened beta-titanium alloy elongated product form from the third temperature range without applying a stress to the stress-relief aged straightened beta-titanium alloy elongated product form during the air cooling.
