Abstract：High temperature oxidation of Fe-23Cr-6Al alloys with and without La, Ceand Y additions at 1300℃ in air has been studied using SEM with a wavelengthdispersive X-ray spectrometer. It is shown that the presence of the cavities formedby the condensation of vacancies caused by the outward diffusion cations resultsin a local detachment at the oxide/substrate interface. This may mainly be respon-sible for the poor oxide adhesion of the alloy without RE. The addition of REchanges the mechanism of growth of the oxide, thus accounts for the improve-ments in oxide adhesion. 收稿日期: 1980-04-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 毛晓禹 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1980/V16/I4/406 [1] Golightly, F.
