The effect of the pulse electric current treatment on residual stresses arising in grinding
Stepanov, G.V.; Babutskyi, Anatolii; Mameev, I.A. (2009)We show experimentally that the passing of a pulse electric current through a strip of stainless steel with a surface layer containing grinding-induced tensile stresses substantially reduces their level. In this case, the ... -
Evaluation of residual stresses in carbon/carbon composites components joined to copper before and after pulse electromagnetic treatment
Stepanov, G.V.; Babutskyi, Anatolii; Mameev, I.A.; Ferraris, M.; Casalegno, V.; Salvo, M. (2011)Results of experimental and calculated evaluation of residual stresses in carbon/carbon composites components produced by joining of carbon fiber reinforced carbon composites to copper are presented. Pulse electromagnetic ... -
Experimental evaluation of pulse electric current effect on residual stresses in composite-to-copper joints
Stepanov, G.V.; Babutskyi, Anatolii; Mameev, I.A.; Ferraris, M.; Casalegno, V.; Salvo, M. (2008)Experimental method for evaluation of residual stress distribution in carbon fiber reinforced carbon composite jointed to copper is presented. Pulse electric current passed through composite-to-copper joint essentially ... -
Experimental evaluation of the electric pulse effect on residual stresses in a Ti-Al-Si-Ag coating
Stepanov, G.V.; Babutskyi, Anatolii; Mameev, I.A. (2008)Experimental results and stress-strain state simulation by the finite element method show that a thin oxidation-resistant coating sputtered onto a titanium alloy substrate develops high-level residual stresses. The electric ... -
Improvement of cyclic fatigue life of metallic materials and welded joints by treatment by pulsed electric current
Stepanov, G.V.; Babutskyi, Anatolii; Mameev, I.A.; Chyzhyk, A.V.; Savitskii, V.V.; Tkachuk, G.I.; Paschin, N.A. (2010)The paper presents experimental data on improvement of cyclic fatigue life of stainless steel and aluminium alloy samples as a result of treatment based on direct passage of electric current through the material, as well ... -
Redistribution of residual welding stresses in pulsed electromagnetic treatment
Stepanov, G.V.; Babutskyi, Anatolii; Mameev, I.A.; Paschin, N.A.; Savitskii, V.V.; Tkachuk, G.I. (2011)Experimental results demonstrate that in an AMg6 alloy specimen after pulsed electromagnetic treatment, a significant decrease and redistribution of residual welding stresses are observed. Numerical simulation corroborates ... -
