摘要

An ultrasound nondestructive (NDE) technique is used to characterize hydrogen concentration (HC) in Zircaloy tubes. This ultrasound-based NDE technique employs a low-frequency PVDF/LFB transducer operated in a z-scan mode to obtain the dispersion relation of guided acoustic waves propagation in the Zircaloy tubes. A Fourier-based signal processing technique is used to obtain the dispersion curves. With this ultrasound technique, the determined dispersion relations are used to determine the HC in Zircaloy tubes with a resolution better than 300 ppm.
