Abstract
A variety of orthorhombic approximant ϵ n (n=6, 16, 22, and 28)-phases exist in Al–Pd–(Mn, Fe, Co, Rh) systems. HREM images and the corresponding electron diffraction patterns show that the ϵ 16 phase in an annealed Al80Pd11Co9 alloy exhibits a locally disordered structure consisting of pentagonal and banana-shaped tiles with an edge length of 0.76 nm. This paper demonstrates a feasible structural model for the ϵ 16 phase in the Al–Pd–Co system by single-crystal X-ray diffraction coupled with HREM.
