Abstract

The paper presents the results of a study for compression deformation of cadmium samples of different purities at room temperature.The analysis of hardening and recovery processes that influence the formation of the structure in the material is carried out. Conditions for starting work and features of dynamic recovery and dynamic recrystallization in samples of technical and distilled cadmium are considered, which result in softening of the material and grain growth in it. The differences in the course of these processes are determined depending on the purity of the initial samples of cadmium. On the basis of the analysis of changes in acoustic parameters (AE activity, amplitude distribution of signals in the AE spectrum, the contribution of signals of different amplitudes to the integrated spectrum of AE),during deformation, we make assumptions about deformation mechanisms that occur at different stages of cadmium deformation. It is shown that the course of dynamic recovery processes during deformation is much more complicated than static recovery ones after deformation and subsequent annealing.
