| 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. |
