In the light of DSC, electronic microprobe and X-ray diffration analyses of the melt-spinning ribbons and the structures of liquid hypoeutectic Al-7%Si, euteclic Al-12.7%Si and hypereutectic A1-18%Si alloys have been investigated. The results show that the Al-Si clusters in liquid hypoeutectic Al-Si alloy, the Si-Si clusters in liquid eutectic and hypereutectic Al-Si alloys exist at low temperatures, however, the size of clusters decreases gradurally with increasing temperature. This process in which inhomogeneous liquid turns into homogeneous one happens in a range of temperatures.
