Description

Frequency dependence of ultrasound attenuation is a sensitive function of composition and microstructural characteristics of materials. For example, while a dense material of a given composition may transmit relatively broad spectrum of ultrasound, its coarse-grained, porous, or defective counterpart may only transmit certain selected frequencies. Investigation of frequency domain spectra can nondestructively provide significant process and applications related information about materials. This paper provides an introduction to Wideband Ultrasonic Spectroscopy (WUS) by utilizing incident ultrasound - characterized by near white frequency spectra - and its applications for ceramic superconductors Non Destructive Characterization (NDC)
