High specific stiffness and strength, isotropic property and ease of production has made the family of discontinuously reinforced metal matrix composites (MMCs) attractive candidate material for aerospace components. Many of the components employed for such applications are subjected to fluctuating stress and strain conditions where an understanding of the low cycle fatigue (LCF) behavior of the material is important. In recent years, study of LCF behavior of discontinuously reinforced aluminum matrix composites has received considerable attention. The cyclic stress response which characterizes the mechanical stability of the intrinsic microstructural features and plastic strain distribution during fully reversed, total strain controlled cycling is an important LCF feature. Some systematic investigations have been carried out to study the effect of variation in particulate/whisker volume fraction on the cyclic stress response of particulate reinforced aluminum matrix composites. The present work reports influence of different sizes of SiCp on the cyclic stress response of Al-Cu-Mg alloy matrix composites.
