Public ISBD [article]  in Materials and corrosion > Vol. 62 N° 8 (Août 2011) . - pp. 760-765 Titre : Influence of heat flux on localised corrosion of stainless steel under boiling conditions Type de document : texte imprimé Auteurs : J. Stoulil, Auteur ; J. Bystriansky, Auteur Année de publication : 2011 Article en page(s) : pp. 760-765 Note générale : Génie Mécanique Langues : Anglais (eng) Mots-clés : Heat  transfer  Pitting  Stress  corrosion  cracking Index. décimale : 620.1 Essais des matériaux. Défauts des matériaux. Protection des matériaux Résumé : The article deals with the influence of heat flux on localised forms of corrosion of stainless steels under the conditions of phase transition on a metal surface. The observations focused on the influence of the initiation and propagation of pitting corrosion and stress corrosion cracking. Pitting corrosion was tested in the environment of 0.6% FeCl3 + 0.3% EDTA + 0.1% HCl, the susceptibility to stress corrosion cracking was verified in 35% MgCl2. The tests proved a negative influence of heat flux on the initiation and propagation of non-uniform corrosion.

Modified EPR-DL method for detection of the spinodal decomposition of 2205 duplex stainless steel / J. Stoulil in Materials and corrosion, Vol. 63 N° 7 (Juillet 2012) 

Public ISBD [article]  in Materials and corrosion > Vol. 63 N° 7 (Juillet 2012) . - pp. 593–597 Titre : Modified EPR-DL method for detection of the spinodal decomposition of 2205 duplex stainless steel Type de document : texte imprimé Auteurs : J. Stoulil, Auteur ; J. Bystriansky, Auteur Année de publication : 2012 Article en page(s) : pp. 593–597 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Duplex  stainless  steel;  EPR-DL;  microhardness;  spinodal  decomposition Résumé : The presented work deals with the possibility of electrochemical detection of the spinodal decomposition of duplex stainless steel's ferritic phase using the modified electrochemical potentiodynamic reactivation double loop (EPR-DL) method. Specimens of FeCr23Ni6Mo3N (2205) steel exposed to the model low-temperature annealing at 420 °C for up to 1000 h were used in the experiment. The specimens were evaluated using potentiodynamic curves measurements in chloride solutions and microhardness measurements. Despite hardening the ferritic phase for up to 1 h, a substantial drop of resistance to attack by chlorides was reported only after 1000 h of annealing. The modified EPR-DL method in 2 M HCl + 0.1 M KSCN solution enables sensitive identification of the spinodal decomposition rate already from early stages.
