论文摘要
在这项工作中，我们使用扩散夫妇方法在Cu-Ag系统中的不对称倾斜晶界进行实验性建立等温纳米曲面的演化。我们研究了Ag溶质过量浓度的依赖性沿晶界沿晶界的纳米形成。最初的晶界将分离为不对称的Ag-Lean片段和富含Ag的对称段（210）段。增加AG的过量会导致富含Ag的小相段的长度增加，而不对称方面的长度保持恒定。由此，我们构建了从局部原子结构，整体倾斜度和Ag溶质过量的实验中得出的晶界纳米图。
In this work, we experimentally establish the isothermal nanofacet evolution at an asymmetric tilt grain boundary in the Cu-Ag system using a diffusion couple approach. We investigate the nanofacet formation along the grain boundary in dependence of the Ag solute excess concentration. The initial grain boundary dissociates into asymmetric Ag-lean segments and Ag-rich symmetric (210) segments. Increasing Ag excess leads to an increase in Ag-rich facet segment length, while the length of the asymmetric facets remains constant. From this, we construct a grain boundary nanofaceting diagram deduced from our experiments relating local atomic structure, overall inclination and Ag solute excess.
