Einfluss von gelöstem Wasserstoff auf die Versetzungsbildung bei plastischer Verformung von Metallen

Hydrogen Interactions with Defects in Materials

“…Increased dislocation densities were observed for example in Pd cold-rolled in the presence of hydrogen, [49,50] or in Fe. [51] A decreased energy of dislocation formation has been observed by a reduced pop-in load during nanoindentation in H-loaded V by Deutges [52] or Tal-Gutelmacher et al [53], in a H-loaded ferritic alloy by Gaspard et al [54] or in deuterium plasma exposed W by Fang et al [55].…”

“…b) TEM micrograph of cold rolled Pd with reduction in thickness by 50 %, and c) charged with 0.005 H/Pd prior to rolling. The dislocation density is significantly increased (micrographs from Deutges, see also 43, 49, 52).…”
