Method for improving the microstructure of titanium alloy wrought products

摘要

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° C. (about 780° to 1020° 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° to 750° C., applying a vacuum to dehydrogenate the material and cooling the dehydrogenated material to room temperature at a controlled rate.
