Abstract
The internal friction in pure aluminum bicrystals with misorientation angles ranging from 5.8\ifmmode^\circ\else\textdegree\fi{} to 44.0\ifmmode^\circ\else\textdegree\fi{} has been investigated. A substantial internal friction peak associated with a grain boundary (GB) appears at medium temperature in each of the bicrystals. The activation parameters of the peak reveal a distinct transition from low- to high-angle boundaries, indicating a structural transition. The difference in activation parameters between low- and high-angle GBs is interpreted by different mechanisms of internal friction.
