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. Key words:  Fe-P-La alloy      internal friction peak      grain boundary peak      Ia      Received:  18 January 1990      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1990/V26/I1/14 1 #12 2 戢景文,赵增祺,贺礼端,耿殿奇.物理学报,1985;34:1620 3 杨植玑,刘沃恒.钢铁,1986;21:6,36 4 Ke TS (葛庭燧).
