Abstract

Рroperties and structure of forgings made of titanium alloy VT3-1, obtained by isothermal deformation under the conditions of the National Research Center «Kurchatov Institute» – VIAM presented in present paper. The draft was carried out according to the scheme of blades with a degree of deformation of 60 % and according to the scheme of disks with a degree of deformation of 80 %. The forgings were subjected to low-temperature, isothermal and double annealing. It has been investigated that the VT3-1 alloy has a high technological plasticity in the temperature range below the polymorphic transformation limit. Stampings show the required level of properties when deformed in the (α + β)-area.
