Microstructure of the modified superalloy K444 after standard heat treatment was investigated by using optical microscopy(OM),scanning electron microscopy(SEM) and energy dispersive spectroscopy (EDS). The primary dendritic distance of these alloys had no significant changes with the increasing of Ga content, and there were no significant changes for the grain size of the three alloys. The content of eutectic was most in the alloy containing 0.01wt.% Ga, and the morphology of eutectic was most irregular. The segregation of other elements was effected by Ga and the elements of Cr and Zr were segregated seriously in the alloy containing 0.01wt.% Ga. ¹Ø¼ü´Ê ×÷Õ߹ؼü´Ê:Superalloy K444; Gallium; Microstructure ×÷ÕßÐÅÏ¢ ͨѶ×÷ÕßµØÖ·: Liu, FG (ͨѶ×÷Õß)               Shenyang Ligong Univ, Sch Mat Sci & Engn, Shenyang 110159, Peoples R China. µØÖ·:               [ 1 ] Shenyang Ligong Univ, Sch Mat Sci & Engn, Shenyang 110159, Peoples R China µç×ÓÓʼþµØÖ·:xiaoxuan1029@163.com; zengchao3245@126.com; alezjj@163.com; lysheng@yeah.net; guoyongan@imr.ac.cn; lzz@imr.ac.cn ²é¿´×÷Õßʶ±ðºÅ×÷Õßʶ±ðºÅ: ³ö°æÉÌ TRANS TECH PUBLICATIONS LTD, LAUBLSRUTISTR 24, CH-8717 STAFA-ZURICH, SWITZERLAND Àà±ð / ·ÖÀà Ñо¿·½Ïò:Materials Science; Metallurgy & Metallurgical Engineering Web of Science Àà±ð:Materials Science, Multidisciplinary; Metallurgy & Metallurgical Engineering ÎÄÏ×ÐÅÏ¢ ÎÄÏ×ÀàÐÍroceedings Paper ÓïÖÖ:English Èë²ØºÅ: WOS:000306295000026 ISBN:978-3-03785-353-5 ISSN: 1022-6680
