Abstract
Near-alpha and alpha+beta titanium alloy components are produced by a process which comprises the steps of forging an alloy billet to a desired shape at a temperature at or above the beta-transus temperature of the alloy to provide a forged component, heat treating the forged component at a temperature approximately equal to the beta-transus temperature of the alloy, cooling the component at a rate in excess of air cooling to room temperature, annealing the component at a temperature in the approximate range of 10 to 20% below said beta-transus temperature for about 4 to 36 hours, and air cooling the component to room temperature.
