Abstract
Certain embodiments of a method for increasing the strength and toughness of a titanium alloy include plastically deforming a titanium alloy at a temperature in an alpha-beta phase field of the titanium alloy to an equivalent plastic deformation of at least a 25% reduction in area. After plastically deforming the titanium alloy in the alpha-beta phase field, the titanium alloy is not heated to or above the beta transus temperature of the titanium alloy. After plastic deformation, the titanium alloy is heat treated at a heat treatment temperature less than or equal to the beta transus temperature minus 20° F. (11.1° C.).
