The hexagonal metastable phase formed in an amophous Ni-P alloy during crystallization exhibits four different orientations. It is shown by SAD that they are four-fold rotation twins around [021]. These four crystals have a common fcc sublattice and their twin relationship may be described by a rotation of 90o about one of the axes of the sublattice.
