| Summary: | This study investigates the valorization of Periwinkle Shell Powder (PSP) as a sustainable and cost-effective reinforcement material in AA6061 aluminum composites. The incorporation of PSP enhances the microstructural, thermal, and mechanical properties of AA6061, demonstrating its potential for improved performance and sustainability. Microstructural analysis using Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) confirms uniform PSP dispersion within the aluminum matrix, contributing to improved homogeneity and fracture resistance. Thermogravimetric Analysis (TGA) and Differential Thermal Analysis (DTA) reveal a 25 °C increase in thermal decomposition temperature and a 30% reduction in weight loss, indicating enhanced thermal stability and suitability for high-temperature applications. Fatigue life testing using S-N curve modeling shows a significant 41% extension in fatigue life, supported by a high coefficient of determination (R^2 = 0.95), highlighting the role of PSP in minimizing crack initiation and propagation under cyclic loading. The findings underscore the successful valorization of PSP through its integration into AA6061, offering environmental and economic sustainability by transforming waste by-products into valuable reinforcement materials. This study demonstrates how the use of PSP improves mechanical performance, thermal stability, and the sustainability profile of AA6061 composites for a variety of engineering applications. |
