Abstrac(-Pure iron specimens anodically oxidized at +600 mV (us see) for one minute were partially reduced with a cathodic current of lOpA/crn" and then reoxidized at the same potential for one hour. The experiment was performed in a boric acid/borate buffer solution at pH = 8.43 at room temperature
It has been found that aging at room temperature or previous straining of hydrogen charged 1020 steel causes an internal friction peak at 105ยฐK to appear, reach a maximum, decrease and finally disappear. This peak has been explained by a model which involves the dragging along of hydrogen atmosphere
