摘要
Abstract
The high temperature oxidation behavior of oxide dispersion strengthened 310 ( ODS-310) alloy was investigated by oxidation test. The morphology, composition and phase of the oxidation layer were analyzed by scanning electron microscopy, energy dispersive spectroscopy and X-ray diffraction. It is found that the oxidation kinetic curves at all the temperatures approximately obey the parabolic law. After oxidizing at 700 and 900 ℃ for 100 h, the alloy shows a good resistance to oxidation. But after oxidizing at 1100 ℃ , the oxide layer becomes thicker with the phenomenon of porosity and discontinuousness, which is harmful to the oxidation resistance. The oxidation degree of the alloy increases with the rising of temperature and the prolonging of time. Energy dispersive spec-troscopy and X-ray diffraction analysis results indicate that the phase of the oxide layer is Cr2 O3 .关键词
