Al2O3/ZrO2(Y2O3) pseudo‐binary eutectic melt may solidify in the dendritic form at the low G/v ratio (thermal gradient G divided by growth rate v) associated with the Y2O3 microsegregation along the monovariant line. Especially, in the system with high Y2O3 content (≥4.5 mol%), an Al2O3/ZrO2/YAG ternary eutectic in situ microstructure growing with a “plane front” will appear at the boundaries of dendritic structures. The volume fraction of the ternary eutectic increases with the increase in Y2O3 content. It was found that the amount of ternary eutectic can be well predicted by the Scheil equation (or nonequilibrium lever rule).

对Al2O3–ZrO2(Y2O3)系统中菌落区中形成的三元共晶组织的认识
Al 2 O 3 / ZrO 2(Y 2 O 3)准二元共熔熔体可能以低的G / v比(热梯度G除以生长速率v)以低的G / v比值以与Y 2 O 3的微观偏析相关的形式凝固单变量线。特别地,在具有高Y 2 O 3含量(≥4.5mol%)的系统中,Al 2 O 3 / ZrO 2/ YAG三元共晶原位微结构以“平面前沿”生长,将出现在树枝状结构的边界。随着Y 2 O 3含量的增加,三元共晶的体积分数增加。发现通过Scheil方程(或非平衡杠杆法则)可以很好地预测三元共晶的量。
