选用第三代镍基单晶高温合金DD33，采用OM、SEM、EDS等分析手段，研究了室温~1100 ℃的热疲劳过程中不同第二取向板式试样圆孔孔周的氧化各向异性行为。结果表明，不同第二取向的第三代单晶高温合金含孔样品经560 cyc热疲劳实验后，冷却孔周围仍未产生裂纹，但其孔周氧化存在明显各向异性特征。并且，相同第二取向试样，孔周不同取向位置氧化层厚度差异明显；不同第二取向试样，孔周不同位置氧化层的厚度分布也不同。造成此差异的本质原因是由于第二取向不同引起样品宏观热应力的差别，导致孔的形状变化趋势与孔周不同位置热应力的差别，与孔周不同位置微观组织差异共同作用的结果。

With the increase of inlet temperatures of the aeroengines, high generation single crystal superalloys were used widely, and more and more complicated structures were employed. Thermal fatigue cracks around the cooling holes were reported to be one of the most important failure mechanisms. In this work, the thermal fatigue behaviors of a third generation single crystal superalloy with different secondary orientations were studied and the effect of secondary orientation on oxidation behaviors around the cooling holes during thermal fatigue tests of samples was investigated by OM, SEM and EDS. The results showed that no cracks was found around the holes even after 560 cyc thermal fatigue tests for both (100) and (110) specimens. But the oxidation behaviors around the holes were different for samples with different secondary orientations, and oxidation layers with different thicknesses were observed around each hole. After 1 cyc thermal fatigue test, the average thickness of oxidation layer around the (110) specimens was almost the same as that of the (100) specimens. After 20 cyc thermal fatigue test, thicker oxidation layers were detected in (110) specimens than that in (100) specimens. Larger difference was observed with the ongoing of the thermal fatigue tests. After 560 cyc, the average oxidation thickness is round 137 μm for (110) specimens, while it is only 88 μm for (100) specimens. Furthermore, the oxidation layer shows different thickness at the different positions of a hole. For (100) specimens, the thickness of oxidation layer decreases in the sequences of [010], [011] and [001] direction, while for (110) specimens it decreases in the sequences of [110], [112] and [001] direction. It was discussed based on the combined effect of thermal stress anisotropy of the sample and local thermal stress anisotropy around the holes, which were caused by crystal anisotropy of single crystals, and the different microstructures around the holes.
