Redistribution of stresses in the header-PGV-1000 steam generator connector weldment under loading after thermal treatment
(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 ...
Effect of pulsed electric current treatment on corrosion of structural metals
(2009)
Results of corrosion tests of structural metals previously treated using pulsed electric current of high density are presented. According to the data obtained, the treatment substantially affects corrosion of metals. In ...
Pulse current treatment effect on the strength of reinforcing steel and its weld joint under impact loading
(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 ...
Influence of pulsed electric current treatment on strength of reinforcing steel and its welds under impact loading
(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 ...
The effect of the pulse electric current treatment on residual stresses arising in grinding
(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 ...
Experimental evaluation of pulse electric current effect on residual stresses in composite-to-copper joints
(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
(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 ...
Effect of a high-density current pulse on the relaxation of shear stresses
(2008)
The procedure and several results of experimental studies on the high-density current pulse-induced relaxation of shear stresses are presented. A significant nonthermal current effect on shear strain kinetics has been ...
