Abstract
Various non-limiting embodiments of the present invention relate to methods of processing titanium alloys wherein the alloys are subjected to deformation above the beta transus temperature (Tβ) of the alloys. For example, one non-limiting embodiment provides a method of processing an alpha+beta or a near-beta titanium alloy comprising 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.
