本文研究了Cu-Ag系中不同晶界类型的晶界润湿相变。用电子背散射衍射法对样品中的银粒子进行了表征。GB特征分布基于重合格点(CSL)模型和GBs的偏向角值。实验结果表明，只有低角度金银和Σ3CSL金银不能完全被熔体润湿。在895℃时，随机高取向(HA)银基玻璃达到完全润湿，只有Σ-11、Σ-5和Σ-13CSL-银基玻璃的润湿温度高于HA-银基玻璃，因此其玻璃能量应低于HA-银基玻璃的能量。
Present work is dedicated to the investigation of grain boundary (GB) wetting phase transition on different types of grain boundaries in the Cu–Ag system. The character of GBs in the samples was determined by the electron backscattering diffraction. GB character distribution was based on the coincidence site lattice (CSL) model and on the values of the misorientation angle of GBs. Experimental results show that only the low angle GBs and the Σ3 CSL GBs do not reach complete wetting by the melt. Random high misorientation angle (HA) GBs reach complete wetting at 895 °C. Only Σ11, Σ5 and Σ13 CSL GBs have a higher wetting temperature than the HA GBs, so their GB energy should be lower than the energy of HA GBs.
