A model for the creep deformation behaviour of single-crystal superalloy CMSX-4

Abstract:

Constitutive equations are constructed for single-crystal nickel-based superalloys. Account is taken of dislocation glide in the channels of the matrix phase (referred to as γ) of the face-centred cubic (fcc) type, dislocation climb at the interfaces with the reinforcing L 12 precipitates (referred to as γ′) and the processes leading to cutting of the interfaces by dislocation ribbons via stacking fault shear of the a 〈 1 1 2 〉 type. A treatment of a 〈 1 1 2 〉 ribbons produced by the combinat...
