摘要： A process for producing a rotor, the rotor formed thereby, as well as turbines in which such a rotor is installed. The rotor is formed by casting an ingot to have first and second regions formed of different alloys that intermix during casting to define a transition zone therebetween. The ingot is forged to yield a rotor forging that contains axially-aligned first and second alloy regions and a transition zone therebetween. The effects of the transition zone can be mitigated by modeling the transition zone and then off-center machining the forging so that the axis of rotation of the machined monolithic rotor is more centrally located with respect to the transition zone.

摘要： A method for non-destructively inspecting a composite structure with a single ultrasonic transducer includes determining a calibration amplitude of ultrasonic transmissions emitted by the single ultrasonic transducer to a reflector in a fluid-filled immersion tank and received back at the single ultrasonic transducer. The method also includes inserting the composite structure into the fluid-filled immersion tank between the reflector and the single ultrasonic transducer. In addition, the method includes scanning the composite structure with the single ultrasonic transducer to measure ultrasonic amplitudes for sound waves traveling through the composite structure, reflecting off the reflector plate and then traveling back through the structure to the single ultrasonic transducer. The measured ultrasonic amplitudes are corrected using the calibration amplitude and other measured transmission losses, and the corrected ultrasonic amplitudes are utilized to generate either or both a digital image showing porosity or a measurement of porosity of the composite structure.
