| 1. A method of processing a titanium alloy comprising:
deforming a body of a titanium alloy at a first temperature (T1) that is above the beta-transus temperature (Tβ) of the titanium alloy;
at least one of: (i) deforming the body at a second temperature (T2), wherein T2 is at least 50° F. greater than T1 to recrystallize at least a portion of the titanium alloy, or (ii) holding the body at T2 for a time period sufficient to recrystallize at least a portion of the titanium alloy; and
deforming the body at a third temperature (T3), wherein T1≧T3>Tβ;
wherein the titanium alloy is one of an alpha+beta alloy and a near-beta alloy, andwherein essentially no deformation of the body occurs at a temperature below Tβ during the method of processing the titanium alloy.
