Abstract
Internal friction was measured to know the changes in the dislocation density and loop length during the steady state creep. Main experimental results are (1) Internal friction of fine grain specimens (d=30µm) is constant during the steady state creep. (2) The decrease in internal friction is observed in medium (d=150µm) and coarse (d=600-850µm) grain specimens, and it is remarkable at high creep stress. The decrease is considered to correspond to that of Al4.
