Abstract—Allowing for the high prospects of the production of initial blanks for the rolling rings of gas turbine engines (GTEs) by centrifugal casting into shell molds and subsequent pulling of hollow blanks from a melt, we choose a forming scheme and temperature–deformation conditions at both final and preliminary stages of the technological cycle of rolling as-cast blanks made of titanium and nickel superalloys. The required service properties of the GTE rolling rings are found to be achieved upon rolling as-cast blanks subjected to preliminary deformation. The proposed method makes it possible to increase the ingot-to-product yield to 0.45–0.50 and to decrease the labor consumed for treatment and the cost of the GTE rings.
