  • Quasi-isothermal forging of a nickel-base superalloy
    Patent number: 6932877
    Abstract: A forging blank of a forging nickel-base superalloy is forged in a forging press having forging dies made of a die nickel-base superalloy. The forging is accomplished by heating the forging blank to a forging-blank starting temperature of from about 1850° F. to about 1950° F., heating the forging dies to a forging-die starting temperature of from about 1500° F. to about 1750° F., placing the forging blank into the forging press and between the forging dies, and forging the forging blank at the forging-blank starting temperature using the forging dies at the forging-die starting temperature, to produce a forging.
