This article establishes the relationship between the parameters of an ultrasonic action on the microstructure and the complex properties of ultrafine-grained brass. Ultrasonic action on brass after radial-shear rolling at certain amplitudes of mechanical stresses helps to relax the nonequilibrium structure of grain boundaries and relieve internal stresses. In this case, the relaxation effect of the structure depends on the amplitude of the ultrasound. It has been shown for the first time that ultrasonic processing is an effective way to relax the structure of highly deformed materials, which leads to an increase in the proportion of large-angle grain boundaries and triple grain joints, without leading to a significant grain growth.
