ABSTRACTBy means of creep property measurement and microstructure observation, the influence of element Ru on the microstructure and creep behaviour of single crystal nickel-based superalloy is investigated. The results show that the plate-like μ phase is precipitated along {111} plane of the Ru-free alloy during thermal exposure at 1080°C and creep at 980°C. And the precipitation of μ phase in the alloy with 6(wt)%Mo and 6(wt)%W may be restrained by adding 2% Ru element. Compared to Ru-free all...

Abstract By means of creep properties measurement and microstructure observation, the deformation and damage behavior of an as-cast TiAl-Nb alloy during creep at temperature near 750 °C were investigated. The results showed that the microstructure of the alloy consisted of lamellar γ/α2 phase, and the boundaries consisted of γ phase located in between lamellar γ/α2 phases with different orientations. In the latter stage of creep, the dislocation networks appeared in the interfaces of lamellar γ/...
