Abstract (en)

Described is a process of producing a component from a gamma prime or gamma double prime precipitation-strengthened nickel-base superalloy. The process includes forming a powder of the superalloy and filling a can (10) with the powder wherein the can includes nickel-chromium-molybdenum-niobium alloy. The can (10) is evacuated and sealed in a controlled environment. The can (10) and the powder are consolidated at a temperature, time, and pressure to produce a consolidation. The consolidated billet is forged at a temperature and strain rate to produce a forging with a uniform fine grain throughout. A further aspect described is a mold including a nickel-chromium-molybdenum-niobium alloy can.
