Abstract Scope	Nickel- and emerging Co-base superalloys derive their excellent mechanical properties from ordered intermetallic precipitates that are resistant to shearing by dislocations that initially glide through the disordered fcc matrix of these two phase materials. Planar fault energies, including anti-phase boundary and superlattice intrinsic and extrinsic faults are important to the design of new compositions. Progress in using first-principles calculations to understand these fault energies will be reviewed. Implications for the design of new CoNi-base superalloys will be discussed.
