A stable one-dimensional quasi crystal was formed in a fully annealed Al65Cu20Fe10Mn5. It was confirmed by stereographic electron diffraction analysis that the one-dimensional quasi crystal has a modified decagonal structure with 6-layer periodicity along the original c axis and 8-layer periodicity in the P direction. Microscopic observation reveals a linking columnar morphology with planar facets around the columns. The columnar direction is identified to coincide with the pseudotenfold(c) axis.
