Abstract

The article presents results of large-sized deformed turbine discs from nickel-based superalloy EK151-ID manufacturing technology development. The developed process provides the manufacturing possibility of large-sized forged discs from nickel-based superalloy with regulated structure and properties using industrial ingots with limited diameter (320 mm). Metal forming simulation engineering software QForm-3D was used in this work.
