ICOSAHEDRAL STRUCTURE OF THE AlCuFe RHOMBOHEDRAL APPROXIMANT PHASE

摘要

Structural models for AlCuFe icosahedral and rhombohedral phases are obtained by decomposition, in perpendicular space, of the atomic surfaces into cells of identical local environment. The models are described in 3D real space and compared to the corresponding H.R.E.M. images obtained on structurally perfect icosahedral and rhombohedral phases.
