研究了三种Fe-Cu合金(含Cu分别为25、50和75wt%)在600～800℃空气中的氧化行为。结果表明它们的氧化均遵循近似的抛物线规律且氧化速率低于组成合金的两纯金属.合金生成颇复杂的氧化膜.基于合金显微组织的双相特征和两金属生成氧化物热力学特性的差异,对氧化过程作了详细地讨论.
The oxidation of three Fe Cu alloys containing 25,50 and 75 wt% Cu respectively has been studied in air at 600～800℃. The oxidation of all the alloys followed parabolic rate law only approximately and oxidized at the rates lower than those of the two pure
