The KKSO multi-phase field model is extended to three dimensions (3D). The modeling and the choice of parameters are confirmed to be correct by tests with low lamellar thickness. With the KKSO multi-phase field model, the morphology evolution of hypoeutectic, eutectic and hypereutectic CBr4-C2Cl6 alloy is studied with low lamellar< thickness. The simulated results showed that the morphology evolution in 3D is similar to that in two dimensions (2D). With the increase of the dimensionless initial lamellar spacings Λ in the range of 0.598-2.336, the sequence of morphology evolution is: lamellar merges→stable growth→lamellar oscillation→lamellar branching. But the critical value of morphology evolution in 3D is smaller than that in 2D due to effect of the third dimension.
