摘要: ＮｉＡｌ－２０ａｔ％Ｆｅ合金的高温氧化与热腐蚀行为王淑荷，郭建亭，赖万慧，谭明晖李辉，孙超（中国科学院金属研究所沈阳１１００１５）１引言ＮＩＡＩ金属间化合物具有熔点高、密度低、热传导性好和抗高温氧化能力优异等特点，是一种很有前途的航空航天耐热结构材料；但由于其室温塑性差，超过５００ｏＣ时的高温强度低、限制了它们的应用Ｉ‘－３ｊ．近年来发现加入Ｆｅ可提高ＮＩＡＩ的低温塑性，并提高其高温强度ｌ‘?...

Abstract：The oxidation and hot corrosion of NiAl-20Fe alloy at 850~1150℃ and 850~950℃ respectivelywere studied. It was shown that both oxidation and hot corrosion of the alloy obey the parabolic ratelaw. The addition of 20at% Fe to intermetallic compound NiAl caused a little drop in oxidation resistance,but a great decrease in resistance against hot corrosion. Compared with NiAl-30Fe, due to a decrease inFe content, an increase in Al content and the addition of Y and Ce, the NiAl-20Fe alloy showed someimprovements in oxidation resistance but little benefit in hot corrosion performance.
