A new orientation relationship OR4 between icosahedral phase and magnesium matrix is described. In this a <tau 10 >-type zone axis is along the matrix hexagonal axis and a fivefold axis along hexagonal < 100 >. This orientation relationship can be derived from the most commonly observed OR1 by a twinning of the icosahedral phase.
