Lattice parameter variation and its effect on precipitation behaviour of ordered Ni2(Cr,Mo) phase in Ni-Cr-Mo alloys

Ni-Cr-Mo based superalloys often precipitate out particles of an ordered Ni2(Cr,Mo) phase in the γ-matrix, whose kinetics varies with composition of alloys. Precipitation of the Ni2(Cr,Mo) phase involves a change in the unit cell from cubic to orthorhombic structure. Lattice misfit strains associate...
