Joint hydrogen susceptibility of 304 SS welded with titanium

Popis výsledku v původním jazyce

Welds of thick plates (304 SS) clad with Ti of commercial purity in as received state and also after subsequent heat treatment and/or after hydrogen charging were investigated under fatigue tests condition (amplitude of 20 Hz), eventually of 40 Hz in case of bimetal without hydrogen charging. After heat treatment charged welds showed higher threshold level than the welds without heat treatment. According the fracture surface EDA (energy dispersed analysis) results, failure predominantly occurred in joint. Hydrogen induced cracking response of bimetal samples showed favourable results both after welding and after subsequent heat treatment. Short and thin cracks were observed, exclusively located in mixed zone, where approx. 16-20 wt. % of Ti using EDA was revealed. By application of monochromatic synchrotron radiation phase analysis confirmed Fe2Ti phase, beside presence of Fe-fcc, Fe-bcc.
