Influence of the Shock Wave of Electric Discharge on the Fatigue Characteristics of Thermally Hardened Steel

The procedure of treatment of thermally hardened steel by pulses of shock waves from electric discharges in water increases its hardness and the limited fatigue strength. As a result of the action of shockwave pulses, the number of dislocations increases. This guarantees the propagation of deformati...

Zusammenfassung:The procedure of treatment of thermally hardened steel by pulses of shock waves from electric discharges in water increases its hardness and the limited fatigue strength. As a result of the action of shockwave pulses, the number of dislocations increases. This guarantees the propagation of deformation in a cycle, which promotes the increase in cyclic fatigue strength
