抄録

Nano-structured Al_xO/i-AlCuFe quasicrystalline composites were synthesized using spark plasma sintering. In this study, the atomized i-AlCuFe powders (nominal with Al₆₄Cu₂₄Fe₁₂) were calcined at 973 K for several hours to obtain the core-shell-like structure with Al_xO and i-AlCuFe. Al_xO layers grew from tens to a hundred of nanometers in thickness as the calcination duration increased. In other words, the Al content decreased within the i-AlCuFe owing to the formation of Al_xO. The loss of Al dominated the electron transportation behavior, which triggered an N-type to P-type transition when the Al content was below 64 at%.
