A numerical model is established to simulate the concentration field in irregular lamel-lar eutectic of Al-Si system.Both the undercooling and spacing are dependent on thegrowth rate and the temperature gradient,and increasing growth rate causes an in-crease of undercooling but a decrease of lamellar spacing,while increasing temperaturegradient leads to a decrease of lamellar spacing.The computed results are in goodagreement with experimental observations.
