摘要: 通过研究Fe-10Al, Fe-5Cr-10Al和Fe-10Cr-10Al(原子分数, %) 合金在900℃的氧化行为, 分析了二元Fe-Al合金形成选择性 氧化铝膜所需的临界铝浓度. 讨论了三元Fe-Cr-Al 合金形成保护性氧化膜的机理, 对于不发生Al的内氧化的 情况, 提出合金中第三组元Cr的作用机制的新解释.
关键词 Fe-xCr-10Al混合外膜选择性氧化    
Abstract:The critical Al content for the selective formation of alumina scales on Fe-Al alloys has been analyzed by investigating the oxidation behavior of binary Fe-10Al and ternary Fe-5Cr-10Al and Fe-10Cr-10Al alloys (atomic fraction, %). A possible interpretation of the effect of the third-element Cr in Fe-xCr-10Al on promoting Al2O3 scale formation not involving a transition from the internal to external oxidation of Al is briefly presented.
Key wordsFe-xCr-10Al    mixed external scale    selective oxidation
