%X Response of the interlamellar of Al-Si eutectic growing under constrained condi-tions to the abrupt change of growth rate has been studied both experimentally andtheoretically.The experiments show that the response is retarded and continuous.Mechanismsof the response are the so-called"cluster-branching"and extension-termination of the clustersof eutectic Si flakes.It is sugggested that the response depends on mass diffusion in liquid andcrystallography anisotropic effect of the solid phases.Uniqueness of steady-state selection ofthe spacing is verified experimentally.A parameter is introduced to characterize the anisotropiceffect.The theoretical analysis is supported from the measured results.
