Abstract Internal oxidation of Ag-xIn alloys (x = 10, 13, 16 at%) was studied in an air atmosphere at a relatively low homologous temperature (240 °C), where lattice diffusion is negligible. After exposure, metallic Ag nodules were present on the surfaces of all alloys, expelled to relieve stress due to internal oxidation, confirming that such coarse morphologies can be produced by short-circuit transport. Crystallographic orientation and grain boundary misorientation were found to influence nodule expulsion tendency, and the propensity for internal or external oxidation. Further analytical TEM characterization was used to study the nanoscale morphology and chemistry of nodules and internal oxide(s).

Ag-xIn合金在低同温下的内部氧化

摘要 Ag-xIn 合金 (x = 10, 13, 16 at%) 的内部氧化在空气气氛中在相对较低的同源温度 (240 °C) 下进行了研究，其中晶格扩散可以忽略不计。暴露后，所有合金的表面都存在金属 Ag 结节，被排出以减轻由于内部氧化引起的应力，证实这种粗糙的形态可以通过短路传输产生。发现晶体取向和晶界取向错误会影响结核排出趋势以及内部或外部氧化的倾向。进一步的分析 TEM 表征用于研究结节和内部氧化物的纳米级形态和化学性质。
