Abstract
A method includes heating an initial titanium alloy comprising a duplex microstructure at a first solution temperature that is below a phase transition temperature of the alloy. Substantially all secondary alpha phase domains may dissolve during the heating. The method also includes cooling the initial titanium alloy at a first cooling rate to form a recrystallized annealed titanium alloy comprising primary alpha phase domains. The method further includes heating the recrystallized annealed titanium alloy to a second solution temperature that is below the phase transition temperature of the alloy. The method additionally includes cooling the recrystallized annealed titanium alloy at a second cooling rate to form a treated titanium alloy comprising the duplex microstructure. The second cooling rate is different than the first cooling rate. A distribution of crystallographic orientations of primary alpha phase domains in the treated titanium alloy may be different than in the initial titanium alloy.
