Effect of pulsed magnetic field pre-treatment of AISI 52100 steel on the coefficient of sliding friction and wear in pin-on-disk tests
(2014-12-01)
Disc specimens manufactured from commercial bearing rollers (AISI 52100 steel, 62–63 HRC) in initial state and after pre-treatment by pulsed magnetic field (PMF) with a magnetic field strength of 1–7 MA/m were tested with ...
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 ...
Effect of pulsed electric current treatment on the corrosion and strength of reinforcing steel
(2012)
The study was carried out in order to evaluate the effect of the pulsed electric current (PEC) treatment on the corrosion as well as on static strength of Polish reinforcing steel. Asreceived St3SX was used for investigations. ...
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 ...
Repair of ship hull structures of aluminium alloy AMg6 using electrodynamic treatment
(2010)
The electrodynamic treatment (EDT) of welded joints from aluminium alloys AMg6 in ship hulls was carried out. The effect of 50...60 % reduction of initial stressed state was obtained at EDT of full-size samples of welded ...
Effect of electric current pulse treatment on the corrosion rate and strength of specimens made of 45 steel
(2010)
The paper presents results of static tensile tests of specimens made of 45 steel after holding them for 100 h in a corrosive medium. It has been shown that due to the pretreatment of specimens with electric current pulse ...
