Precipitation of topologically close-packed phases in a high Mo-containing nickel-base single crystal superalloy aged at 1100 °C for 1000 h was investigated by the spherical aberration-corrected transmission electron microscope. The selected area electron diffraction, super EDS and highresolution transmission electron microscopy were used to analyze the TCP precipitates in this study. Compositions of the growth front and the internal phase of the TCP phase are inconsistent, while the P phase and Laves are almost identical, confirming that the P phase is transformed from the Laves phase rather than through the nucleation grew up.
