The complication of symbiotic region relied on the sensibility of microstructures on solidification conditions, while the multiplicity of morphology was decided by crytical characters of eutectic phases. When the interior disturbance or unstablity of exterior condition exist some unusual microstructures and defects appeared in alloy.Correspondent: LI Shunpu, research assistant, Institute of Physics, Chinese Academy of Sciences, Beijing 100080 Key words:  directional solidiflcation      eutectic symbiotic region      preferred orientation.Al-Si alloy      Received:  18 February 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/I2/47 1ElliottR,EutecticSolidificationProcessing．Butterworth,1983:29421992:1703胡汉起．金属凝固原理．北京:机械工业出版社,1991:1194李顺朴,陈熙琛,OM93全国相变学术会论文集．北京,1993:415C1975:1476FleminthMC著、关玉龙．屠宝洪,许诚信译．凝固过程．北京:冶金工业出版社．1981:115 [1] SUN Lijing; DONG Lianke; ZHANG Jinghua; HU Zhuangqi(Institute of Melal Re- search; Chinese Academy of Sciences; Shenyang)(Manuscript received 3 1 August 1993; in revised form 19 October; 1993).
