Abstract: Effect of thermal history in meit on inhomogeneity of microstructure in RS Al-Fe based alloy is studied. It is showp tha t the microstructure of welledistri buted 20~40nm bec Al12(Fe,V)3 Si dispersion phase on a supersatu ratedo-Al solid solution matrix is obtained at melt temperature l250~1350℃for l0 minutes in RS microstructure.

Key words: melts, rapid solidification, aluminum alloys, microstructure
