摘要：
The effect of vanadium (V) addition on the tensile - and stress rupture-property at room temperature and 750℃, and the microstructure evolution of GH4061 alloy, including grain size, carbide and γ' /γ'' phase etc. were investigated by means of tensile- and stress rupture-testing, OM, SEM, TEM and electrochemical extraction and phase analysis of precipitates. The results show that V addition can promote the precipitation of MC-type carbide and γ' /γ'' phase, and refine the grain size slightly. With the increase of V content, the lattice constant of γ matrix increases, the mismatch between γ matrix and γ' phase decreases, and the coarsening of γ' /γ'' phase at 750℃ is restrained. The addition of V does not have significant influence on room temperature tensile property, but apparently benefits the tensile strength and rupture life at 750℃. Furthermore, the GH4061 alloy with 0.4% (mass fraction) V addition shows the best stress rupture property at 750℃. © All right reserved.
