dc.description.abstractHydrogen-induced variation of stacking fault energy (SFE) of a CrMnFeCoNi high-entropy alloy (HEA) was quantitatively evaluated by transmission electron microscopy (TEM) using weak-beam dark-field (WBDF) technique. Width of Shockley partial dislocations turned out to increase after hydrogen absorption, which indicates that hydrogen decreases the SFE of the alloy: from 31.5 +/- 3.5 to 22.5 +/- 2.5 mJm(-2) by introduction of hydrogen into the lattice with approximate concentration of 115 wppm. This report provides the first direct observation of stacking faults under the influence of hydrogen in a face-centered cubic metallic structure.-
