The results show that the distribution of the RE-rich second phase particles is bimodel, the amount of the smaller particles (20─80 nm in diameter) is considerably larger than that of the large particles (200─300nm in diameter). Based on a diffusion－controlled growth kinetics equation, the formation mechanism of the bimodel distribution of the RE-rich second phase particles in the alloy is explained by using the disturbing theory. Key words:  rapid solidification      Ti-55 alloy      RE-rich second phase      bimodel.      Received:  18 September 1995      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/Y1995/V31/I9/417 1李阁平,刘羽寅,李东．钛科学与工程,第八届全国钛合金会议,上海,1993:5882韩东,曹名洲．钛科学与工程,第八届全国钛合金会议,上海,1993:5933SastrySML．MeschterPJ．O’NealJE．MetallTrans,1984;15A:14514SuryanarayanaC,FroesFH,RoweRG．InternationalMaterialsReviews,1991;36(3):855SastrySML,PengTC,BeckermanLD．MetallTrans,1984;15A:14656KonitzerDG,MuddleBC,FraserHL,ScriptaMetall,1983;17:9637KonitzerDG,MuddleBC、FraserHL．MetallTrans,1983;14A:19798KonitzerDG,StanleyJT,LorettoMH,FraserHL．ActaMetall,1986;34(7):12699WangSH．JMaterSci,1986:21:222410KonitzerDG,StanleyTT,LorettoMH,FraserHL．ActaMetall,1986;34:126911SastrySM,PengTC,BeckeimanLP．MetallTrans,1984;15A:146512GreenwoodGW．ActaMetall,1965;4:243 [1] LIANG Chen, WANG Xiaojuan, WANG Haipeng.
