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 ...

Improvement of the wear resistance of EN8 steel by application of alternating magnetic field treatment

Akram, Sufyan; Chrysanthou, Andreas; Babutskyi, Anatolii; Montalvão, Diogo; Whiting, Mark J.; Modi, Om Prakash (2021-04-30)

In the present paper, the tribological properties of untreated and magnetically treated EN8 medium-carbon steel were studied. Tribological tests were performed using a pin-on-disc friction and wear tester. The alternating ...

Improvement of the wear resistance of nickel-aluminium bronze and 2014-T6 aluminium alloy by application of alternating magnetic field treatment

Akram, Sufyan; Babutskyi, Anatolii; Chrysanthou, Andreas; Montalvão, Diogo; Whiting, Mark; Pizurova, Nada (2021-09-15)

The present work has used an alternating magnetic field treatment at ambient temperature to improve the wear resistance of nickel-aluminium bronze and aluminium alloy 2014-T6. Pin-on-disc wear tests under lubricating ...

Influence of pulsed electric current treatment on strength of reinforcing steel and its welds under impact loading

Kruszka, L.; Stepanov, G.V.; Zubov , V.I.; Babutskyi, Anatolii (EDP Sciences, 2009)

Results of static and impact tension tests of as-received reinforcing steel specimens, specimens with weld joints in their test portion, as well as specimens after high-density pulse current pretreatment are presented. As ...

Pulse current treatment effect on the strength of reinforcing steel and its weld joint under impact loading

Kruszka, L.; Stepanov, G.V.; Zubov, V.I.; Babutskyi, Anatolii (2009)

We present results of static and impact tension tests of as-received reinforcing steel specimens, specimens with weld joints in their test portion, as well as specimens pretreated by high-density pulse current. As test ...

Pulse electric current effect on mechanical properties of titanium aluminide produced by the self-propagating high-temperature synthesis technique

Stepanov, G.V.; Babutskyi, Anatolii; Chyzhyk, A.V.; Gromov, V.E. (2012)

We present results of study on the effect of pulse electric current treatment on bending strength and hardness of intermetallic titanium aluminide produced by the self-propagating high-temperature synthesis technique. It ...

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 ...

Redistribution of stresses in the header-PGV-1000 steam generator connector weldment under loading after thermal treatment

Kharchenko, V.V.; Stepanov, G.V.; Kravchenko, V.I.; Kobel'skii, S.V.; Babutskyi, Anatolii; Trunov , N.B.; Piminov, V.A. (2009)

Additional heating of a thickened portion of the steam generator connector during postrepair thermal treatment of the header-connector weldment leads to a decrease in residual tensile stress levels. It is shown that during ...
