Abstract
Investigation results indicating the influence of high-density impulse electric current on impact toughness of Charpy specimens manufactured from low carbon steel are presented. It is shown, that impulse electric current treatment causes a considerable growth of impact toughness of the steel, and type of material fracture is changed from brittle mode to ductile mode.
Keywords
