摘要 |
A superalloy made of a forging nickel-base superalloy such as Rene TM 88DT or ME3 is forged in a forging press (40) having forging dies (52, 54) made of a die nickel-base superalloy. The forging is accomplished by heating a superalloy workpiece (56) to a forging temperature of from about 1700 DEG F to about 1850 DEG 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. <IMAGE> |
