Isothermal forging of nickel-base superalloys in air |
摘要 |
A superalloy made of a forging nickel-base superalloy such as Rene(TM) 88DT or ME3 is forged in a forging press having forging dies made of a die nickel-base superalloy. The forging is accomplished by heating to a forging temperature of from about 1700° F. to about 1850° F., and forging at that forging temperature and at a nominal strain rate. The die nickel-base superalloy is selected to have a creep strength of not less than a flow stress of the forging nickel-base superalloy at the forging temperature and strain rate.
