abstract = {Premature failures of magnesium matrix composites (MMCs)
reinforced with ceramic particles generally originate from
stress concentrations in particle-agglomerated regions. This
study investigates how the spatial distribution of SiC
particles (SiCp) affects internal stress states in a
SiCp/Mg-5Al composite through in-situ synchrotron tensile
testing combined with multi-scale crystal plasticity
modeling. Simulation of four microstructures with coarse
intergranular SiCp (5 μm), refined intergranular SiCp (2
μm), intergranular-dominated SiCp, or balanced hybrid SiCp
have performed. Key findings show that refining
intergranular SiCp (from 5 μm to 2 μm) increases particle
stress heterogeneity by $65 \%.$ Conversely, intragranular
dispersion reduces stress localization. Meanwhile, the
balanced hybrid distribution minimizes von Mises stress
variability in SiCp. The critical resolved shear stress
(CRSS) ratio of non-basal to basal slip in the composite is
determined to be 3.3–4.3. Plastic deformation of the
composite is primarily governed by non-basal dislocation
slip due to its fiber texture. We emphasize the importance
of combining matrix grain refinement and alloying to
optimize reinforcement dispersion and strain compatibility
within MMCs. The related strategies may synergistically
improve both ductility and strength of MMCs.},
