Influence of electropulsing treatment on residual stresses and tensile strength of as-quenched medium carbon steel

Abstract

With the development of the technique of the high energy electric current pulse, the electropulsing treatment (EPT) is used in manufacturing more frequently. The effects of EPT on residual stresses and tensile strength of as-quenched medium carbon steel are investigated by experiments. The results show that EPT can reduce residual stresses, and improve tensile strength of the specimens. With the increase of the current density, the residual stresses decrease, and the tensile strength increases. The increase of the tensile strength is due to the decrease of the residual stresses.
