ABSTRACT:
A dual alloy radial turbine rotor with high tensile strength hub material exposed in the saddle regions between the blades to prevent fatigue that causes cracks in the saddle regions is manufactured by producing the hub with additional material at the outer portions of a frustoconical rear portion of the hub. After diffusion bonding of the outer surface of the hub to the mating inner surface of the blade rim, portions of the blade rim in the saddle regions are machined away to produce finished saddle configurations with the high tensile strength hub material exposed.
