      abstract     = {The microstructure of Mg-Al-Ca alloys consists of a hard
                      intra- and intergranular eutectic Laves phase network
                      embedded in a soft α-Mg matrix. For such heterogeneous
                      microstructures, the mechanical response and co-deformation
                      of both phases under external load are not yet fully
                      understood. We therefore used nano- and microindentation in
                      combination with electron microscopy to study the
                      deformation behaviour of an Mg-3.68Al-3.8Ca alloy.We found
                      that the hardness of the Mg2Ca phase was significantly
                      larger than the α-Mg phase and stays constant within the
                      measured temperature range. The strain rate sensitivity of
                      the softer α-Mg phase and of the interfaces increased while
                      activation volume decreased with temperature. The creep
                      deformation of the Mg2Ca Laves phase was significantly lower
                      than the α-Mg phase at 170 °C. Moreover, the deformation
                      zone around and below microindents was dependant on the
                      matrix orientation and was influenced by the presence of
                      Laves phases. Most importantly, slip transfer from the α-Mg
                      phase to the (Mg,Al)2Ca Laves phase occurred, carried by the
                      basal planes. Based on the observed orientation relationship
                      and active slip systems, a slip transfer mechanism from the
                      soft α-Mg phase to the hard Laves phase is proposed.
                      Further, we present implications for future alloy design
                      strategies.},
