摘要：
The effect of hydrogen on the stacking-fault energy has been evaluated in a 310 austenitic stainless steel. The stacking-fault energy was calculated from measurements of the radius of curvature of dislocation nodes, which were imaged using weak-beam conditions. Preliminary results indicate that the presence of 40 torr of hydrogen gas in a transmission electron microscope equipped with an environmental cell, causes an increase in node spacing which corresponds to about a 19% reduction in the stacking-fault energy.
