摘要
The liquid structure of Co79.5Sn20.5 eutectic alloy has been investigated by means of X-ray diffraction. The result shows that the liquid structure of Co79.5Sn20.5 alloy displays quite stable from 1350℃ to 1150℃ although the short-range order increases with temperature decreasing.In addition,the correlation between the liquid structure and solid structure also has been analyzed by"the nanocrystal model".It is shown that the melt of Co79.5Sn20.5 alloy consists ofβCo3Sn2 clusters andβCo clusters, indicating that the liquid structure and solid structure of Co79.5Sn20.5 eutectic alloy are strikingly similar.
