AbstractThe precipitation of B2 -NiAl/C14-Laves eutectics with a volume fraction of similar to 0.5% in the interdendritic gamma/gamma' eutectic regions of a 3 wt% Ru-containing single crystal Ni-based superalloy has been characterized. It is found that the eutectic reaction Liquid ->+Laves (C14) takes place at the end of solidification process. Transmission electron microscopy image shows that numerous fine "butterfly-like" Laves precipitates with a size of similar to 30 nm are embedded in the coarse blocky -NiAl, suggesting a coherent or semi-coherent interface between these two phases. The crystallography relationship of and between Laves and -NiAl phase was obtained in terms of selected area electron diffraction patterns. Electron probe microanalysis results reveal that 3 wt% Ru addition makes more Al, Ta and other refractory elements segregate to the interdendritic regions, which is believed to be the main reason for this undesirable eutectic reaction. In addition, the formation of these eutectics is found to be strongly affected by solidification conditions.
