Results of investigation into the effect of electrodynamic treatment (EDT) using single pulses on the kinetics of elastic strains and stressed state of heat-resistant steels are given. The experimental procedure is presented and a laboratory EDT unit is described. It has been established that treatment using single discharges initiates the fields of elastic compression-tension strains in the material treated, their values being in direct dependence on the discharge voltage. It is shown that EDT can be employed for relaxation of the stressed states of heat-resistant steel structures.
Keywords: electrodynamic treatment, heat-resistant steels, stress-strain state, electron-dislocation interaction, flat sample, cylindrical sample, specific pulse energy
