摘要

Abstract

Here we investigated the nucleation of the Re

Ru-rich δ phase affected by stacking faults in the γ phase in a 4th generation Ni-based single crystal superalloy during the service at 800°C. The stacking faults in the γ phase were rich in Re and Ru

similar to the observed δ phase. And the stacking fault regions possessed a similar structure to the δ phase

promoting the transformation from γ phase to δ phase. Furthermore

the calculation results indicated that Ru had more significant promoting effects on the δ phase precipitation than Re

providing a reference for the alloy design.
