摘要	The effects of solution time and long-term aging on microstructure evolution and mechanical properties of a traditional nickel-based single crystal superalloy under different heat treatment conditions were studied. The results demonstrate that the best heat treatment regime is 1310 degrees C/4 h (AC)+1130 degrees C/4 h (AC)+899 degrees C/16 h (AC). After the solution treatment, the precipitation of adverse phase of TCP has been avoided and thus the preferable microstructure is obtained with small size and high degree of cubic of strengthening gamma ' phase. The difference in creep rupture life and elongation is slight under different heat treatment regimes. During the deformation, the brittle TCP phase is broken first, demonstrating that it is not the crack initiation. However, the weak carbide/matrix interface in inter-dendrites is the source of cracks.
