Abstract
The accumulation of deformation and acoustic emission upon high-temperature loading of aluminum has been studied. It has been established that in aluminum the accumulation of deformation in the course of a thermomechanical cycle brings about the formation of deformation bands whose density is of a pronounced quasi-periodic character depending on the temperature. The minimum and the maximum of the density of deformation bands correspond to the temperature of jumplike development of deformation and to the monotonic character of deformation accumulation, respectively. The monotonic accumulation of deformation is accompanied by a monotonic growth of the root-mean-square voltage of acoustic emission, while the jumplike development of deformation, by high-amplitude single acoustic signals. The amplitude of single acoustic signals correlates with the strain rate.
