摘要：
A new process to refine the microstructure of α+β type Ti alloys was developed by using hydrogen as a temporary alloying element. It involves hydrogenating the alloys below the hydrogenated β transus temperature about 0-40K, air cooling to room temperature and then dehydrogenating at 948 K. Ti-6Al-4V and Ti-5Al-2.5Fe alloys treated by this new process show much refined microstructure, and the yield strength, ultimate strength as well as the elongation increase 8-15, 5-13 and 7-14% respectively.
