Precision Extrusion of Hollow Turbine Vanes of Oxide Dispersion Strengthened Nickel Chromium Alloy by the Filled Billet Method.

Abstract

Precision extrusion of hollow vanes of oxide dispersion strengthened nickel chromium alloys was demonstrated on subscale specimens using a modification of the filled billet method. The desired <100> microstructure was attained after heat treatment of extruded vanes. Stress rupture life at 2000 F at 11 ksi exceeded 100 hours. A full scale processing sequence based on subscale results is proposed. (Author)
