METHOD OF PRODUCTION OF VANADIUM-BASED ALLOYING COMPOSITIONS Russian patent published in 1997 - IPC

FIELD: metallurgy of nonferrous metals and alloys for production of high-quality alloyed titanium alloys. SUBSTANCE: the offered method includes heating of melt, cooling and crystallization. Heating of melt is carried out to temperature of true solution equalling 2070-2270 K held for 10-20 min, and cooled at the rate of 1-10 K/s. EFFECT: provision of modification of alloyed titanium alloys containing vanadium without introduction of foreign impurities and additional refining of alloying composition from nonmetallic inclusions. 2 dwg, 1 tbl
