The thermodynamics and kinetics of the internal oxidation in dilute Cu-Al alloy are investigated.The internal oxidation of copper alloy containing 0.2~1.2 Wt pct Al is studied in the temperature range from 1073 K to 1273 K. A related equiIibrium diagram is drawn. A mathematic model of oxidation layer depth is developed on the base of the experimental results. The experiments and investigation show that the formation rate of the internal oxidation layer is mainly controlled by the diffusion of O in matrix, the O concentration on the surface and the Al concentration in the alloy
