摘要： To achieve improved ultrasonic testing coverage of a finished machined component, the present invention applies a method for modifying a finished machine component forging for ultrasonic inspection. A forging envelope may be constructed in the shape of a right circular cylinder that surrounds a machine component forging. Then material may be added to the forging envelope in the direction of the forging equal to about 2 times a wavelength of an ultrasonic inspection device. Additional material may then be added to an inspection surface of the forging envelope equal to the dimension of a transducer dead zone, if the forging cannot be inspected ultrasonically from two opposing surfaces in the forged direction. Lastly, material may be added to the forging envelope in a direction perpendicular to the forging direction equal to a transducer footprint plus the break edge radius.

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 system and method that allows for the immersion ultrasonic inspection of test samples that cannot be immersed in a fluid (e.g., water) bath. A test sample is encapsulated in a sealed evacuated bag made of nonporous flexible material. A portion of the nonporous flexible material is in contact with the surface area of the test sample where the ultrasound wave or beam will impinge. Then the sealed bag with test sample inside are immersed in an acoustic coupling medium, as is an ultrasonic transducer. The transducer is directed to transmit an interrogating ultrasound wave or beam through the vacuum bag into the component being inspected at the area of interest. The sealed bag prevents contact between the inspected component and the acoustic coupling medium.
