摘要	The effect of withdrawal rates on the solidification microstructure of a single crystal Ni-based superalloy containing ruthenium was investigated. The results show that with the increase of the withdrawal rate, the as-cast microstructure of the single crystal alloy transforms from coarse dendrite to finite dendrite. Meanwhile, the size of the gamma' particles decreases, segregation of alloying elements for the dendrite and interdendritic regions tends to be reduced, the volume fraction of gamma-gamma' eutectic and NiAl-based beta phase decreases gradually. In addition, the withdrawal rate has little influence on the phase transformation temperature of the superalloy.
