Ultrasonic double backscatter techniques are widely used to evaluate microstructure and detect flaws during high frequency ultrasonic inspections. For typical microstructure of beta-forged Ti-6Al-4V alloy, a new double scattered response (DSR) model that considers the lamellar microstructure within grains and the grain size distribution along the major axis is developed based on a previous DSR model. Numerical results show that the amplitude of ultrasonic scattering decreases because of elongated grains and major axis distribution of grain size. This work is anticipated to play an important role in microstructural characterization research associated with ultrasonic scattering for the beta-forged Ti-6Al-4V alloy.
