	The very high cycle fatigue properties of the Ni-based single-crystal superalloy CMSX-4 coated with an MCrAlY type coating and grit-blasted were studied at 1000 \&deg;C, 20 kHz and R = -1. A recrystallized layer thicker than the size of the larger casting pores (\&gt;50 \&mu;m) drastically reduces the fatigue life without environmental influence. The recrystallized layer and roughness introduced by grit-blasting degrades the environmental resistance of the alloy and the resultant fatigue life. The fatigue life of the coated specimens is also greatly reduced from damage accumulation in the interdiffusion zone by grain boundary cracking, oxidation and internal nitridation.

	A systematic and accelerated methodology for alloy design is demonstrated by combining combinatorial synthesis, high-throughput oxide scale characterization, computational density functional theory, and CALPHAD database calculations. By applying this strategy to the senary Co-Ni-W-Al-Cr-Ta material system, a novel \&gamma;/\&gamma;\&$\#$39; alloy exhibiting a superior combination of properties has been identified. Properties include a \&gamma;\&$\#$39; solvus near 1200 \&deg;C, continuous \&alpha;-Al2O3 scale formation after 1 h in air at 1100 \&deg;C, and comparable density to 2nd-generation commercial Ni-base superalloys. This novel alloy SB-CoNi-10 has a nominal composition of 39.8Co \&ndash; 36.5Ni \&ndash; 13.2Al \&ndash; 1.0W \&ndash; 6.0Cr \&ndash; 3.5Ta at.\%, and its properties are compared with other recently studied Co-, CoNi-, and Ni-base \&gamma;/\&gamma;\&$\#$39; alloys.
