Abstract: Thesolidification processof Al 7 5% Mg Zn alloys wasstudiedin thepaper.The Zn contentand cooling rate werechanged andtheirinfluenceson as cast microstructure were measured by different methods. The solute segregation during nonequilibrium solidification process wascalculated byternary Scheilequation which wasin good agreement with experimentresulte.

Key words: aluminum alloy, as cast microstructure, nonequilibrium solidification
