Abstract The AB2 type Laves phases with cubic MgCu2 and
hexagonal MgZn2 structures are investigated by
partial least square (PLS) method and some criteria for
classification of the two structures of Laves phases
are obtained. It is found that for nontransition-transition
and transition-transition alloys the valence electron densities
of component elements are significant in influencing their
Laves phase structures, and for transition-lanthanide
(actinides) alloys the valence electron density of the atom at B
position is
the most important factor influencing their Laves phase
structures. Besides, the effects of both valence charge
and atomic radius on Laves phase structures are in
opposition to each other in transition-lanthanide (actinides)
alloys.
