Abstract

Based on the experimental study of superplastic deformation parameters, a technology was developed for producing near-net-shape compressor blade forgings for gas turbine units from Ti-6.2Al-2.5Mo-l.5Cr-0.2Si-0.5Fe. The mechanical properties of these blades are higher than those of blades produced by conventional methods, and the anisotropy coefficient is reduced. The improved properties of the blades can be attributed to the isotropy of mechanical properties resulting from the homogeneous fine-grained equiaxed structure produced throughout the blade volume.
