Velocity and attenuation of ultrasonic wave in Al–Al2O3 nanocomposite and their correlation to microstructural evolution during synthesizing procedure
Non-destructive pulse-echo ultrasonic testing was conducted to measure ultrasonic parameters, i.e. longitudinal velocity (Vl), shear velocity (Vs) and attenuation coefficient (α) in Al–Al2O3 nanocomposites. Elastic constants were also determined using the relationship between Vl and Vs. The aim was...
