摘要

研究了Y元素对含铼镍基单晶高温合金高温恒温氧化行为的影响。采用静态增重法研究了Y对900、1 000和1 100℃下合金的氧化动力学的影响，并采用扫描电镜和X射线衍射等手段分析了氧化产物的结构和形貌。结果表明，含Y和不含Y合金在900、1 000和1 100℃下的氧化级别均为完全抗氧化级。Y含量的增加虽然对900℃和1 000℃的氧化增重影响很小，但明显降低了1 100℃的氧化增重，这是由于Y的添加增加了α-Al

的连续性，提高了氧化膜保护效果。

Abstract

The effects of Y on the isothermal oxidation behavior of a nickel-based single crystal superalloy containing Re at 900 ℃

1 000 ℃ and 1 100 ℃ were investigated by static weight gain method. The microstructure and morphology of oxidation were analyzed by X-ray diffraction（XRD） and scanning electron microscope（SEM）. The results indicate that oxidation grade of the alloy with yttrium and without yttrium are all complete oxidation resistance grade at 900 ℃

1 000 ℃ and 1 100 ℃. The oxidation weight gain at 900 ℃ and 1 000 ℃ are hardly affected

while that at 1 100 ℃ is significantly reduced by the increase of Y content

which is attributed to the continuity increase of α-Al

caused by Y addition

enhancing the protective effect of oxide film.
