用Ｍ１７和Ｋ３合金作对比，着重研究了低偏析镍基铸造高温合金Ｍ４１的高温氧化性能进行了恒温氧化、循环氧化以及Ｘ射线衍时（ＸＲＤ）、扫描电镜（ＳＥＭ）、能谱分析（ＥＤＡＸ）等实验，结果表明，Ｍ４１合金的氧化速度随温度升高以加速度方式增长，但小于Ｋ３合金，温度越高，差别越大；在１０００℃以上，Ｍ４１合金的氧化动力学规律明显偏低于抛物线规律．Ｍ４１合金循环氧化性能优于Ｍ１７合金，氧化膜粘附性较好，基本不脱落，在过渡氧化阶段，该合金主要形成Ｎｉ和Ｃｒ的氧化物：稳态氧化阶段的氧化层主要由连续致密的Ｃｒ２Ｏ３，外氧化层和树根状Ａｌ２Ｏ３内氧化层构成．内氧化随时间延长，温度升高而加剧，离外氧化层／基体界面越近，内氧化物颗粒越细、越多．
Using M17 and K3 alloy as contrast, the high temperature oxidation performance of low segregation Ni-based superalloy M41 was investigated. The effects of oxidation temperature, cyclic oxidation, XRD, SEM, EDAX ) And other experiments. The results show that the oxidation rate of M41 alloy increases with the increase of temperature, but less than that of K3 alloy, the higher the temperature, the greater the difference; at above 1000 ℃, the oxidation kinetics of M41 alloy is obviously lower than Parabolic law. M41 alloy has better cyclic oxidation performance than M17 alloy. The oxide film has good adhesion and little non-falling off. In the transitional oxidation stage, the alloy mainly forms oxides of Ni and Cr: the oxide layer in the steady state oxidation stage is mainly composed of continuous dense Cr2O3, the outer oxide layer and the root-like Al2O3 oxide layer. The internal oxidation increases with time and temperature increases, and the closer the outer oxide / matrix interface, the finer the inner oxide particles.
