在 ７６０－１０５０℃和７８０－１１５ ＭＰａ范围内，选择不同温度和应力配合进行了持久拉伸实验，研究了温度和应力的变化对试件断裂寿命的影响以及温度、应力和断裂寿命与共格相特征尺寸（基体相γ水平通道宽度、筏形析出相γ厚度）和试件延伸率及断面收缩率的关系．结果表明，在各实验条件下，γ除了进行定向粗化以外，相邻数列γ还可沿外应力轴方向发生不同程度的纵向合并，尽管在较高的温度下外应力较低，γ纵向合并的程度增大巨形态趋于不规则对实验结果进行了分析与讨论
In the range of 760-1050 ℃ and 780-115 MPa, different temperature and stress were selected to conduct the long-term tensile test. The effect of temperature and stress on the fracture life of the specimen and the influence of temperature, stress, fracture life and coherent phase The relationship between the feature size (the width of the γ phase channel, the γ-phase thickness of the raft), and the elongation and the reduction of area of the specimens. The results show that, in addition to the directional coarsening, the adjacent sequence γ may have different degrees of vertical integration along the direction of the external stress axis under the experimental conditions. Although the external stress is lower at higher temperature, The degree of macro-morphology tends to irregular The experimental results were analyzed and discussed
