Ag-7.49wt%Sn-1.16wt%Cu合金在800°C下在空气中内部氧化。结果表明，随着离试样表面距离的增加，内氧化层中弥散颗粒的尺寸和硬度逐渐增大。内氧化层深度与氧化时间呈抛物线关系。内氧化层中颗粒的断裂应力随颗粒半径的增大而增大。冷轧是有效的内氧化，因为内氧化层中的氧的扩散增加。合金的内氧化是一个反应扩散过程。
Ag–7.49 wt%Sn–1.16 wt%Cu alloy was internally oxidized in air at 800°C. The results showed that the size of dispersed particles and hardness in internally oxidized layer became larger with the distance from the surface of the specimens. The relationship between the depth of internally oxidized layer and oxidation time followed a parabolic law. The fracture stress of particles in internally oxidized layer increased with the particle radius increasing. Cold rolling was effective for internal oxidation because of the increased diffusivity of oxygen in internally oxidized layer. Internal oxidation of the alloy was found to be a process of reaction diffusion.
