Abstract

We have utilized the technique of EXAFS to investigate the local environment of Fe and Mo in Fe₀₂Co₅₀Al₄₈ and in Mo₀₂Ni₅₀Al₄₈ respectively. We find that Co atoms drive competing Fe atoms to the "Al type" sites, whereas Mo precipitates as small particles of BCC Mo. Our results are of possible significance in relation to findings by others of ductility enhancement in ternary doped β phase NiAl.
