The results differing from that of previous works are discussed in term of cast process and microstructure. Key words:  directionally solidified superalloy      thin-wall effect      stress-rupture property      microstructure      Received:  18 April 1997      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/Y1997/V33/I4/370 1Doner M,Heckler J A.Proceeding 6th International Symponsition.on Superalloys.Warrendale,PA:The Metallurgical Society,1988:653 2韩希鹏,管文彪,宋克强,李晋年.铸造高温合金论文集,北京:中国科学技术出版社,1993:194 3Baldan A.Malerials for Advanced Power Engineering,Dordrecht,Netherlands:Klawer AcademicPhublishers,1994;Part I:863 4穆寿昌.北京科技大学学报,1991;增刊:656 5Fleury E,Remy L.Metall Mater Trans,1994;25A:99 6Winstone M R,Northwood J E.Solidification Technology in the Foundry and Cast House.Coventry,England:The Metals Society,1980:298 7刘忠元,李建国,史正兴,傅恒志,佘力,陈荣章,王罗宝。材料工程,1995 6:15 8陈荣章。航空制造工程,1990;4:22 [1] WANG Lei, LIU Mengya, LIU Yang, SONG Xiu, MENG Fanqiang.
