A thermodynamic diffuse interface analysis predicts that grain boundary transitions in solute absorption are coupled to localized structural order-disorder transitions. An example calculation of a planar grain boundary using a symmetric binary alloy shows that first-order boundary transitions can be predicted as a function of the crystallographic grain boundary misorientation and empirical gradient coefficients. The predictions are compared to published experimental observations.
一种热力学弥散界面分析预测，溶质吸收中的晶界转变与局部结构有序-无序转变相关联。使用对称二元合金对平面晶界进行的示例计算表明，一级边界转变可作为晶体学晶界取向差和经验梯度系数的函数进行预测。将这些预测结果与已发表的实验观察结果进行了比较。
