摘要： A dual alloy cooled turbine wheel is manufactured by casting a hollow cylinder (1) of first nickel-base alloy material with high creep resistance to produce directionally oriented grain boundaries. A preform (2) of a second nickel-base alloy material with high tensile strength and high low-cycle-fatigue strength is diffusion bonded into the bore (1A) of the hollow cylinder (1) by subjecting the cylinder and preform to hot isostatic pressing. The resulting cylindrical block (10) is cut into thin precisely flat wafers (10A). A plurality of alignable holes (11, 11B) for forming fluid cooling passages are photochemically etched into the individual wafers. The wafers then are laminated together by vacuum diffusion bonding techniques, with the holes (11, 11B) aligned to form fluid cooling passages. The resulting laminated block (10B) is machined to produce the turbine wheel (10C) with turbine blades (13) through which the cooling passages (11, 45) extend.
