The thermoelectric properties of icosahedral AlPdRe quasicrystals obtained by replacing Re with transition metals have been studied in according with the guiding principle of Weakly Bonded Rigid Heavy Clusters (WBRHCs) . The dimensionless figure of merit (<I>ZT</I>) was increased 2.6 times from 0.08 to 0.21 by Fe substitution for Re in the icosahedral AIPdRe quasicrystals. It is then possible to improve the thermoelectric performance of <I>i</I>-AlPdRe by searching over a wider range of composition, including the addition of a fourth element or fourth and fifth elements.
