The formation of decagonal and icosahedral phases in Al75−xPd25Crx (x <3 at.%) quasicrystals

Abstract
An Al75Pd25 decagonal (D) phase changes to an F‐type icosahedral (I) phase by the substitution of 3 at. % Cr for Al in a rapidly solidified state. The coexisting I and D phases in a rapidly solidified Al73Pd25Cr2 alloy have a close orientation relationship, in which a tenfold axis of the D phase coincides with a fivefold axis of the I phase.
