ÐThe e€ect of hydrogen in solid solution on the edge/screw character of dislocations has been investigated by deforming samples of high-purity aluminum in a gaseous hydrogen environment in situ in a controlled environment transmission electron microscope. Solute hydrogen was found to stabilize edge segments of dislocations, which inhibited, and in some cases stopped dislocations from cross-slipping. Removal of hydrogen from the sample allowed the cross-slip process to continue. These… CONTINUE READING
