摘要：

The development of continuous Al2O3 scales on alloys via selective oxidation is an extremely effective approach to obtain high-temperature oxidation resistance. Depending on the alloy system, it may be necessary to optimize the selective oxidation process. For all alloy syst erns, improvements in oxidation resistance can be obtained by optimizing the type and concentrations of reactive elements and by controlling the concentration of sulfur.
