【摘要】 研究了铁基ODS合金MGH956在1250℃高温下的氧化行为,分析了氧化皮的成分、形貌和结构,重点研究了纳米级的稀土氧化物弥散颗粒对MGH956合金氧化行为的影响。结果表明弥散颗粒能够加速合金表面氧化膜的形成,细化氧化膜晶粒,显著提高合金的氧化抗力。更多还原

【Abstract】 The 1250℃ high temperature oxidation behavior in MGH956 alloy was studied.The composition,topography and microstructure of the oxidation film were analysed.The effects of dispersion particles on oxidation behavior was studied in focus.It was found that the dispersion particles could speed the formation of oxidation film and turn oxidation film grain smaller,thus remarkable improve oxidation resistance ability in MGH956 alloy.更多还原
