Abstract
Irreversible change of grain boundary structure due to the different hydrogen charging of annealed and cold worked iron of high purity was studied by internal friction measurements of grain boundary relaxation. Two relaxation modes are involved in the main process of grain boundary relaxation : high temperature mode associated with the GB sliding, and low temperature mode associated with the motion of near grain boundary dislocations.
