چکیده انگلیسی
The effect of Ru on γⲠprecipitation behavior and evolution in single crystal superalloys with different Ru contents were investigated by scanning electron microscopy with energy dispersive spectroscopy, 3D atomic probing, differential scanning calorimetry. The results show that the solvus of the γⲠphase decreases gradually with increasing Ru content in the alloys by casting or by the same solution and aging treatments, the alloy with a larger Ru content yields a smaller γⲠphase. The addition of Ru increases the growth rate and coarsening rate of the γⲠphase. Ru mainly distributes in the γ phase, which causes more Re and Mo partition into the γⲠphase, increasing the absolute value of mismatch and the rafting rate of the γⲠphase.
