The objective of Phase II of this manufacturing technology program was to produce the 2nd stage blade of the Avco T-55 engine for static evaluation using the isothermal roll forge process. Blades were produced in AM-350 alloy using two roll-forge passes of the energy efficient, microprocessor controlled process. The blades met the fatigue, tensile and metallurgical requirements of Avco specifications.
