Al2O3-YAG-ZrO2 eutectic ceramic plates 10 mm in width, 2.4 mm in thickness and 100 mm in length were directionally grown by micro-pulling down technique under different growth rate (0.1-1 mm/min). The effects of the solidification rate on the crystallographic orientation and microstructure properties were analyzed in consideirable detail. The microstructure spacing lambda depends on the pulling rate v following the law: lambda=7.2v 1/2 where lambda is in mu m and v in mu m/s. For low growth rate (nu < 0.25), the ternary eutectic plates had homogeneous and regular microstructures and higher pulling rate heterogeneity in the morphology corresponding to colonies presence. The annealed plates did not undergo chemical reaction but slight grain growth was observed. (C) 2016 Elsevier B.V. All rights reserved.
