  • System and methods for determining sensitization of alloy by measuring and correlating ultrasonic parameters
    Patent number: 10416120
    Abstract: The present invention relates generally to a system and methods for testing sensitization of alloy nondestructively. More specifically, the present invention relates to a system and methods for determining the sensitization of an alloy by measuring ultrasonic parameters of the alloy using ultrasonic techniques, and correlating the measured ultrasonic parameters. In certain embodiments, the ultrasonic measuring techniques include pulse-echo and resonant ultrasound spectroscopy. Certain embodiments use ultrasonic measuring techniques to measure shear-wave velocity, compressional-wave velocity, and attenuation coefficient of compressional waves. One preferred embodiment correlates measured ultrasonic parameters including shear-wave velocity, compressional-wave velocity, and attenuation coefficient of compressional waves to determine the sensitization of alloy.
