Abstract

The microstructure and deformation mechanism of two "replacement of Re by W" type low-cost second-generation nickel based single crystal superalloys after fracture at 982℃/248 MPa and 1070℃/137 MPa were investigated by SEM and TEM. The results show that the stress rupture properties of two alloys both reached the level of the second-generation single crystal superalloys; After fracture γ′ phases connected and combined to form "N-type" rafted structure, and the degree of γ′ phases distortion increased with the distance from the fracture. Under the same conditions, the raft degree of γ′ phases in 8.5W+1.0Re alloy was lower than that in 8.0W+1.5Re alloy; At 1070℃/137 MPa, the interfacial dislocation networks of the two alloys became denser; However, the dislocation networks of 8.0W+1.5Re alloy were denser than that of 8.5W+1.0Re alloy, a<010> superdislocations shearing into the γ′ phases were observed after fracture in 8.5W+1.0Re alloy under both conditions; The unstable fracture of the two alloys was mainly ascribed to a/2<110> dislocations in γ matrix shearing into the rafted γ′ phases, which intensify the deformation of rafted γ′ phases, and results in initiation and propagation of microcracks at the γ/γ′ interface, eventually leading to the fracture of the alloy; The interfacial dislocation networks and a<010> superdislocations could both improve the creep resistance of the two alloys.

Key words: metallic materials nickel based single crystal superalloy stress rupture properties deformation mechanism rafted γ′ phases
