%X The grain boundary internal friction in Fe-P and Fe-P-La alloys con-taining a little Cu has been studied. The internal friction is obviously reduced byLa added even 0.584-0.722 wt-%. The grain boundary peak migrates toward thehigh temperature and a small internal friction peak occurs. The grain boundaryinternal friction seems to be interpreted by movement, under stress, of both thedefects of atomic size, namely point defects, in grain boundaries and their clusters.
