abstract = {The mechanical behaviour of Mgsingle bondAl alloys can be
largely improved by the formation of an intermetallic Laves
phase skeleton, in particular the creep strength. Recent
nanomechanical studies revealed plasticity by dislocation
glide in the (Mg,Al)2Ca Laves phase, even at room
temperature. As strengthening skeleton, this phase remains,
however, brittle at low temperature. In this work, we
present experimental evidence of slip transfer from the Mg
matrix to the (Mg,Al)2Ca skeleton at room temperature and
explore associated mechanisms by means of atomistic
simulations. We identify two possible mechanisms for
transferring Mg basal slip into Laves phases depending on
the crystallographic orientation: a direct and an indirect
slip transfer triggered by full and partial dislocations,
respectively. Our experimental and numerical observations
also highlight the importance of interfacial sliding that
can prevent the transfer of the plasticity from one phase to
the other.},
