Abstract
This study investigated the evolution of the hardness and structural characteristics of an Al-6.5%Ag-2%Cu alloy. The alloy was subjected to deformation by route Bc equal-channel angular pressing followed by artificial aging at 150 and 200 °C. Analysis of the aging curves with and without prior deformation indicates a significant increase in hardness attributed to severe plastic deformation rather than to the formation of precipitates during aging. Transmission electron microscopy analysis revealed the presence of nanometer precipitates, characterized by their morphology as γ/γ’ and θ/θ’ phases. Further investigation of the alloy’s mechanical properties and microstructural changes could provide deeper insight into its behavior under various conditions, potentially improving its applicability in engineering applications.
期刊介绍：
ASM International''s Journal of Materials Engineering and Performance focuses on solving day-to-day engineering challenges, particularly those involving components for larger systems. The journal presents a clear understanding of relationships between materials selection, processing, applications and performance.
The Journal of Materials Engineering covers all aspects of materials selection, design, processing, characterization and evaluation, including how to improve materials properties through processes and process control of casting, forming, heat treating, surface modification and coating, and fabrication.
Testing and characterization (including mechanical and physical tests, NDE, metallography, failure analysis, corrosion resistance, chemical analysis, surface characterization, and microanalysis of surfaces, features and fractures), and industrial performance measurement are also covered
