AB  - 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
