Microstructural examinations have enabled identification of particles and grain structure of the materials. The results indicated that tensile properties of the composites significantly improved in the yield strength, UTS and elastic modulus, on incorporation of hard, brittle ceramic particles as compared to unreinforced counterparts. On the other hand, ductility decreased considerably due to the brittle ceramic particles. The results were discussed in the light of microstructures. © Shiraz University.eninfo:eu-repo/semantics/closedAccess2124 Al-alloyCompositesMMCSiCpTensile behaviorArticle282 B2392482-s2.0-4644275416N/A
