The experimental results indicated that the loss elastic modulus had different temperature varying rate and vibration frequency dependent behaviour from the storage elastic modulus, and the dependence of internal friction on temperature varying rate and vibration frequency has been discussed in the viewpoint of the complex elastic modulus. To analyse the complex elastic modulus may be more helpful to study the first-order phase transition than to only analyse internal friction. Key words:  internal friction      complex elastic modulus      eutectoid decomposition      mechanical property      interface      Zn-Al alloy Correspondent LIU Junmin      (Department of Physics      Zhongshan University      Guangzhou 510275)      Received:  18 August 1996      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/Y1996/V32/I8/785 1ZhangJX,PungPCW,ZengWG．PhysRev,1995;B52:268ZhangJX,YangZY,FungPCW．PhysRev,1995;B52:2782DelormeJF,SchidR,RobinR,GobinP．JPhysColloq,1971;32(C2):1013DejongheW,BatistDR,DeleayL．ScrMetall,1976;10:11254王业宁,杨正举,祝和,马进超．南京大学学报(自然科学版),1963;2:15马应良,葛庭燧．物理学报,1963;20:7216张进修,罗来忠．物理学报,1988;37:353,3637WangYN,ChenXiaohua,ShenHuimin．In:KeTSed．,ProcIntConfonInternalFrictionandUltrasonicAttenuationinSolids,Beijing:AcademicPublishers,1989:3058BidauxJE,SchalierR,BenoitW．ActaMetall,1989;37:8039LiuHY,JonesH．ActaMetallMater,1992;40:200310NuttalK．JInstMet,1971;99:26611TorisakaY,KojimaS．ActaMetallMater,1991;39:94712刘军民,张进修．物理学报,待发表13NowickAS,BerryBS．AnelasticRelaxationinCrystallineSolids．NewYork:AcademicPress,1972:24714HermidaEB．PhysStatusSolidi,1993;B178:371 [1] GONG Shengkai, LIU Yuan, GENG Lilun, RU Yi, ZHAO Wenyue, PEI Yanling, LI Shusuo.
