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