Abstract

Various non-limiting embodiments of the present invention relate to methods of processing alpha + beta or near-beta titanium alloys wherein the alloys are subjected to deformation above the beta transus temperature (T&) of the alloys. The method of processing an alpha + beta or a near-beta titanium alloy comprises deforming a body of the alloy at a first temperature (T1) that is above the Tβ of the alloy; recrystallizing at least a portion of the alloy by deforming and/or holding the body at a second temperature (T2) that is greater than T1; and deforming the body at a third temperature (T3), wherein T1 >T3 >Tβ; wherein essentially no deformation of the body occurs at a temperature below Tβ during the method of processing the titanium alloy.
