Isothermal Roll Forging of T55 Compressor Blades

Abstract

The objective of this manufacturing technology program was to demonstrate feasibility to produce T55 compressor blades by isothermal roll forging within 0.010 inch of drawing tolerances. This objective was accomplished through process definition and application to blades in Ti6Al4V for proofing and in AM- 350 steel for the T55 engine. Satisfactory structure and mechanical properties were achieved in AM-350 steel after isothermal rolling. Cost analyses showed good potential for progressive cost reduction with continued work over present methods of production.
