| description |
Experimental testing revealed that adding ceramic nanoparticles of alumina Al2O3 to the aluminum alloy AA2017 by a casting route significantly enhanced the mechanical and fatigue properties. Understanding the behavior of materials under cyclic loads is necessary; engineers can ensure that structures and components perform reliably throughout their intended lifespan. This work explicitly focuses on the role of these nanoparticles in the fatigue behavior of the aluminum matrix (AA2017) and the resulting (AA2017 – 0.8 wt. %, Al2O3) nanocomposite. The test influences of the stress- number of cycles S – N curves showed that cyclic stress below the endurance limit for fatigue, followed by cyclic stress above the endurance limit, decreased the fatigue life and strength. Specifically, the fatigue life was decreased more than twice for the nanocomposite and about 4% for the base metal, while the fatigue strength was lowered by (140.8 to 137.8) MPa for the matrix and (155.5 to 142.4) MPa for the final product of (AA2017 – 0.8 wt. %, Al2O3).
