4.4. Nomenclature for Types I and II S phase
As part of the present discussion, we will attempt to provide a nomenclature for the observed phases that takes the
present findings into account and is as much as possible consistent with the past literature. In many publications [1–
3,8,10,21],S0 and S in (SQ1) have been considered to have
the same structure and the same orientation relationships
with aluminium matrix (i.e. no rotation). The only distinction is the small difference in lattice parameters, with S 0
being semi-coherent and S non-coherent with aluminium
matrix. This distinction, however, is not supported by the
majority of experiments, and many recent publications
make no distinction between the S0 and S phases
[14–19,22], instead considering the two types to be indistinguishablein termsof lattice structureand lattice parameters.
To take account of this and other recent developments in
understanding of the precipitation sequence in these alloys,
