| Abstract | Generally, elevated solution heat treatment temperature decreases the residual dendritic segregation of refractory elements (i.e. Re and W) and suppresses the precipitation of deleterious topologically close-packed (TCP) phases in Ni-based superalloys. However, in the present study, elevated solution temperature resulted in an abnormal increase of TCP phases in a Ni-based single crystal superalloy after long-term thermal exposure at 900 degrees C. Microstructural analysis suggested that higher supersaturation in gamma phase which promoted the formation of TCP phases was induced by the increased gamma' precipitation after heat treated at elevated solution temperature.
