Abstract

The article describes main factors allowing to extend the application area for VT8-1 alloy in GTE parts for rotary – fan drives and compressors of high and low pressure. Comparative characteristics of the mechanical properties (strength, ductility, toughness, FCGR) of disks die forgings of VT8-1 and VT6 alloys with respect to large-sized forgings drives for the fan and first stage of low pressure compressors , as well as drives of the HPC of VT8-1 and VT9 alloys (characteristics of strength, fracture toughness, FCGR, heat resistance) applicable for parts with working temperature up to 500°С are presented.
