Abstract Scope	Co-base superalloys strengthened with L12 precipitates possess excellent high temperature creep properties in single crystal form. However, the engineering application of these alloys will require a balanced suite of properties. The elastic properties of Co-base and Co-Ni base alloys measured by resonant ultrasound spectroscopy and fatigue behavior of single crystals will be presented. Combinatorial experiments that have identified oxidation-resistant compositional ranges will be reviewed. Implications for alloy design across the Co-base to Co-Ni base compositional regime will be discussed.
