The paper presents the results of a study of compressive deformation of high purity cadmium samples at room temperature with different deformation rates: 6.9$\cdot10^{-5}$, 5.6$\cdot10^{-4}$ and 4.2$\cdot10^{-3}$ s$^{-1}$. The analysis of hardening and recovery processes, affecting the formation of the structure in the material, is carried out. The conditions for starting work and the features of dynamical recovery and dynamical recrystallization of high-purity cadmium, which result in softening of the material and grain growth in it, are considered. The differences in these processes passing are found depending on the rate of deformation. Based on the analysis of changes in acoustic parameters (acoustic emission (AE) activity, amplitude distribution of signals in the AE spectrum, contribution of signals of different amplitudes to the integral spectrum of AE), we make assumptions about deformation mechanisms that occur at various stages of cadmium deformation.

Key words: cadmium, deformation mechanisms, dynamical return, dynamical recrystallization, acoustic emission (AE), amplitude distribution of AE signals.
