Abstract: The tensile properties of 2124Al alloy composites reinforced with various sizes of SiC particles were investigated at room temperature. The size of SiC_p was changed from 0.2μm to 48.0μm with an identical volume fraction of 20%. The results show that the relative density of the composite decreased with increase of the SiC_p size from 3.0μm to 48.0μm, whereas 0.2μm SiCpreinforced composite has the lowest relative density. The pore density, interparticle spacing, SiC particle cracking, SiC_p/Al interfacial debonding, the distribution of SiC particles, in the composites are considered as factors to determine the failure behavior of the composites.
