摘要
The regular lamellar eutectic growth is simulated by Monte-Carlo (MC) method. The growth velocity R is evaluated from the solid-liquid (S-L) interface configuration. The relation between the calculated lamellar spacing A and R shows a good consistence with the Jackson-Hunt (JH) theory when R is not very low; the calculated lambda(2)R decreases with decreasing R, when R is fairly low, which supports the universal scaling relationship between lambda and R. The simulated composition in front of the S-L interface shows a clear spatial oscillation around the average composition c(0), and the composition oscillation decays significantly with increasing distance from the S-L interface.
