Abstract An analysis for the formation conditions of the massive phase in Al-Fe-V-Si alloy was carried out by RS tests and TEM observations. The results show. the temperature range in which the massive phase occurs in is 1173-1103 K. The mixed structure of massive phase and microcellular will occurs when the cooling rate of the melt (the critical cooling rate) in the above temperature range and the cooling rate after RS starting.And the mixed structure of massive phase and coarse cellular will occurs when during whole RS process.(Correspondent: CHEN Longqing, professor, Department of Material, Zhengzhou Institute of Technology,Zhengzhou 450002)

Key words: rapid solidification solidification temperature cooling rate Al-Fe-V-Si alloy
