ABSTRACT:
A method for improving the microstructure of wrought titanium alloy material which comprises the steps of hydrogenating the material at a temperature near or above the titanium-hydrogen eutectoid of 815.degree. C. (about 780.degree. to 1020.degree. C.) to a hydrogen level of about 0.50 to 1.50 weight percent, cooling the thus-hydrogenated material to room temperature, heating the thus-cooled, hydrogenated material to a temperature of about 650.degree. to 750.degree. C., applying a vacuum to dehydrogenate the material and cooling the dehydrogenated material to room temperature at a controlled rate.
