abstract = "GE Aviation under the US Air Force Hybrid Disk Contract (FA8650-10-C-5225) investigated a powder nickel alloy design space in search of an alloy composition to increase the state of the art temperature capability for rotating disk applications to 1450 oF (788 °C). The eleven alloy Design of Experiments (DOE) explored the relationship between chemistry and mechanical properties (creep, tensile, ductility, dwell LCF, cyclic fatigue crack growth & static fatigue crack growth) as well as identified key attributes around gamma prime precipitation temperatures, phase stability and long term exposures and stability of gamma prime. Regression analysis of the data obtained indicates that increasing W and decreasing Cr and Ti are desirable for improved high temperature strength and creep capability.",
