Abstract研究了011取向的镍基单晶高温合金在750~980℃温度范围和200~680 MPa应力下的蠕变断裂特征.在扫描电镜上对各种实验状态下的蠕变断口和纵向剖面进行了详细观察.研究发现:在低温750℃和中温870℃不同初始蠕变应力条件下,枝晶间区亚晶界处不规则γ'/γ界面是裂纹主要萌生场所,这些已萌生的裂纹在与外加应力轴垂直的(011)面上沿〈110〉和〈100〉两个方向扩展;980℃不同初始应力条件下,裂纹主要在合金中显微疏松孔洞处萌生,沿与外应力轴垂直的方向扩展.观察750℃和870℃不同应力状态蠕变试样的纵向剖面,对亚晶界区不规则γ'相面积分数的测量和计算表明,用面积分数表征该合金011...
