Abstract

It is demonstrated that long-range ordering can be utilized to synthesize a nanoscale superlattice of Ni₂(Cr,Mo) in a Ni-18.6 at.% Mo-15.1 at.% Cr. The superlattice is distinguished by high strength and high ductility. This behavior has been correlated with the crystallography of the disorder-order transformation, which favors deformation by twinning on the {1 1 1} planes of the parent face-centered cubic structure.
