Effect of transient heating of the outer surface of a radial crack-containing ring specimen on its brittle fracture resistance
(2012-07)
Experimental studies on the effect of transient heating of the outer surface of radial crack-containing ring specimens from 45 steel on their fracture toughness are described. Such a treatment contributes to an increase ...
Pulse electric current effect on mechanical properties of titanium aluminide produced by the self-propagating high-temperature synthesis technique
(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 ...
Effect of a pulsed electromagnetic field on stress relaxation in concentrator-containing flat specimens
(2012)
Experimental results of evaluating the pulsed electromagnetic field effect on tensile stress relaxation in specimens with hole a concentrator are presented. The pulsed electromagnetic field is shown to induce local inelastic ...
Redistribution of residual welding stresses in pulsed electromagnetic treatment
(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 ...
Evaluation of residual stresses in carbon/carbon composites components joined to copper before and after pulse electromagnetic treatment
(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 ...
Evaluation of the residual stresses in the welded joint of the header with a connecting pipe of a steam generator after additional thermomechanical treatment
(2010)
We present the results of numerical evaluation of the possibility of application of additional thermomechanical treatment to the welded joints of the headers with connecting pipes of PGV-1000 steam generators from WWER-1000 ...
Improvement of cyclic fatigue life of metallic materials and welded joints by treatment by pulsed electric current
(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 ...
Electric pulse current effect on stress-strain state in the notch vicinity in a cantilever beam under cyclic bending
(2010)
Calculation results of the thermal effect assessment induced by electric pulse current on stress variation in the edge notch vicinity in a metal cantilever beam under cyclic bending are presented. The results obtained ...
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 ...
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 ...
