ABSTRACT:
The microstructure of forged titanium alloy components is improved by beta-transus heat treating the components, hydrogenating the components at an elevated temperature, cooling the thus-hydrogenated components to room temperature, dehydrogenating the components at an elevated temperature and cooling the dehydrogenated components to room temperature.
