pulse EM treatment, microdefects healing, high-energy electromagnetic field.

The article presents the results of a study of treatment short pulses of a high-energy electromagnetic field on samples from zinc. The aim of the work was to study the possibility of healing micropores and microcracks inside the material. The description of the used equipment and experimental methods is given. The obtained experimental data are analyzed. Based on the study of the microstructure of the metal before and after exposure to the field, The assumption is confirmed that under the considered treatment in zinc, there may be a decrease in the damage(porosity) of the material and, as a result, a significant increase in the limit plastic strain before fracture. It is shown that the decrease in porosity is not the result of recrystallization, which practically does not occur under the studied influence.
