ABSTRACT:
The disclosure relates to a turbine rotor and method of manufacture thereof. A plurality of blades having dovetails at the radially inner ends thereof are arranged in a circumferentially spaced circular array. A metallic hub is cast about the dovetails of said blades which are metallurgically bonded by the operation. Alternatively, the blades may be joined to the hub thereafter by an electron beam weld that extends axially to the rotor.
