| 摘 要： | 对两种晶粒形状的HK40炉管材料,研究了晶粒形状及碳化物对蠕变裂纹扩展速率的影响。发现当加载方向与柱状晶轴向垂直时,柱状晶材料的蠕变裂纹扩展抗力低于等轴晶材料。二次碳化物对裂纹扩展速率的影响依赖于晶粒形状。

| Abstract: | The influence of two different grain shapes and carbides in the HK40 alloy,the material for use of furnace tube, on the rate of creep crack growth has been investigated.The material of columnar grain is inferior resistance against creep crack growth to that ofequiaxial grain, when the load line is perpendicular to the columnar grain axis. The influenceof secondary carbides on the rate of creep crack propagation is dependent upon the grain shape. |
