| 英文摘要 | The effects of ruthenium (Ru) addition on the microstructures of Ni-based single crystal superalloys as-cast, post-heat treated and long term aged (at 1100 degrees C) were investigated by optical microscope (OM), scanning electron microscope (SEM) and transmission electron microscope (TEM). The results show that Ru addition increases the content of eutectic and reduces primary dendritic arm spacing. The solution heat treatment of the 3Ru alloy is more difficult. The stacking fault energy of the gamma matrix obviously decreases after Ru addition, and the extended dislocations in the gamma matrix may impede the movement of the following dislocations during plastic deformation and improve the mechanical properties significantly. During long term aging at 1100 degrees C, Ru addition has no significant effects on the rafting process, and does not change the main type of topologically close-packed (TCP) phase. However, the precipitation process of TCP phase is suppressed after Ru addition. As the aging time is prolonged, the suppression effect of Ru addition is weakened (over 500 h). |
