METHOD OF HOT ROLLING OF TITANIUM-ALLOY RODS Russian patent published in 1998 - IPC

Abstract RU 2108876 C1

FIELD: plastic metal working, namely production of high quality rods of double-phase titanium alloys with wide range of diameters for manufacturing parts of aerospace vehicles. SUBSTANCE: rod blank is deformed by discrete elongation values equal to 1.08- -1.5. Said bank is heated only up to temperature of $$$ zone. Such method allows to make rods with normalized macro- and microstructure providing stable degree of mechanical properties in rod section. EFFECT: enhanced quality of rods. 2 dwg
