The spheroidisation mechanism of iron compounds has also been investigated. Key words:  Al-Si alloy      iron compound      heredity      spheroidizing mechanism      Received:  18 October 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/I10/1062 1《铸造有色合金及熔炼》联合编写组.铸造有色合金及熔炼.北京:国防工业出版社,1980 2赵莹.特种铸造及有色合金,1994;(1):114 3刘相法,边秀房等.特种铸造及有色合金,1994(10):17 4 Bian X F,Zhang G H.
