The influence of volume fraction (17 and 25 vol%), particulate size (2.5 and 15 µm) of reinforcement particles and strain ratio (R=0, R=0.5 and R= -1) are examined for 2124 Al-alloy-T4 composites. Increasing the content of SiCp results in the degradation of strain control fatigue properties. The monotonic and cyclic stress-strain response of the 2124Al – (25 vol% 2.5 µm) SiCp composite was significantly altered by strain ratio values. Fatigue cracks frequently initiated from intensively stress concentrated regions. Increasing volume fraction and particle sizes result in early crack initiationeninfo:eu-repo/semantics/openAccessComposites, FatigueLow cycle FatigueArticle2632652742-s2.0-0036247718N/A352517
