摘要 

利用透射电镜和场发射扫描电镜研究了两种不同Ru含量(3%和5%，质量分数)的第四代镍基单晶高温合金DD22在1130 ℃长期时效过程中γ′相形貌演化、TCP相析出和界面位错网的演化情况。研究结果表明：在完全热处理后5Ru合金比3Ru合金的γ′相尺寸更小，形状更规则，γ/γ′相界面的错配度更大，高Ru含量使合金Re，Mo等元素出现反分配现象；5Ru合金在1130 ℃长期时效过程中γ′相粗化速率、溶解速率和形筏速率均低于3Ru合金；5Ru合金在长期时效1000 h后仍没有TCP相析出，而3Ru合金在时效50 h后便析出TCP相，随着长期时效时间延长，TCP相数量增多，尺寸增大；与3Ru合金相比，长期时效1000 h后5Ru合金γ′/γ界面位错网更加致密和规则；综上所述，Ru的元素反分配作用和低的扩散系数使5Ru合金比3Ru合金表现出更高的组织稳定性。

Abstract：

The morphological evolution of γ′ phase, the precipitation of TCP phases and the evolution of the interfacial dislocation networks in DD22 nickel-based single crystal superalloys with different Ru contents (3% and 5%, mass fraction) were investigated by transmission electron microscopy and field emission scanning electron microscopy during long-term aging at 1130 ℃. The results show that γ′ phase of 5Ru alloy are smaller in size and more regular in shape than that of 3Ru alloy. The mismatch of γ/γ′ phases is larger in 5Ru alloy, and the high content of Ru causes the reverse distribution of elements such as Re and Mo. During long-term aging at 1130 ℃, the coarsening rate, dissolution rate and rafting rate of γ′ phase in 5Ru alloy are lower than those of 3Ru alloy. There is still no TCP phase precipitation in 5Ru alloy after long-term aging for 1000 h, while a small amount of TCP phase is precipitated in 3Ru alloy after long-term aging for 50 h. With the prolongation of long-term aging time, the number and size of TCP phases both increase. Compared with 3Ru alloy, the interfacial dislocation networks of 5Ru alloy are denser and more regular after long-term aging for 1000 h. Above all, the reverse distribution of elements and low diffusion coefficient of Ru make 5Ru alloy exhibit higher microstructural stability than 3Ru alloy.
