METHOD OF MANUFACTURING ARTICLES FROM TITANIUM AND ITS ALLOYS WITH SUBMICROCRYSTALLINE STRUCTURE

摘要

FIELD: metallurgy, particularly, technology for improvement of properties of submicrocrystalline materials; applicable in manufacture of structural articles in aircraft industry, medicine and microelectronics. SUBSTANCE: method includes saturation of blank with hydrogen, blank thermomechanical treatment to impart the desired shape, and dehydrogenating vacuum degassing annealing at temperature of 250-300 C conducted by electron irradiation. Technical result of invention consists in performance of full degassing of hydrogen from titanium alloys without recrystallization of material to preserve high operating characteristics inherent to alloys with submicrocrystalline structure. EFFECT: higher efficiency. 2 dwg
