It involves hydrogenating the alloy at 0—40K below the hydrogenated β transition temperature, air cooling to room temperature and dehydrogenating at 948K. Ti-6Al-4V and Ti-SAl-2.5Fe alloys treated by the process show much refined microstructures, and the yield strength, ultimate strength and elongation increase by 8—15, 5—13 and 7—14% respectively.
