摘要：
The oxidation of binary Cu-Al alloys containing 1.4, 2.2, 3.0, 4.2 and 6.5 at.% Al was studied at 1073K in 0.1 MPa O-2. The increase of the Al content produced first a transition from internal oxidation of aluminum to the growth of mixed Cu + Al external oxide scales and later on to the formation of external Al2O3 scales. The critical Al contents required for the transitions between different oxidation modes are predicted and compared with the experimental results.
