| Abstract Scope |
This study examines 6061-RAM2 aluminum alloy produced by wire arc additive manufacturing, focusing on fatigue and tensile behavior as influenced by heat treatment, microstructure, and inoculants. Microstructural features and their evolution through heat treatment are characterized to understand phase and particle distributions and their impact on mechanical response. The relationship between these microstructural factors and mechanical performance under cyclic and monotonic loading is analyzed in detail. Results demonstrate promising fatigue properties at lower stress amplitudes, alongside favorable monotonic tensile properties exhibiting isotropic behavior. The presence of inoculants contributes to refined microstructure and improved mechanical performance. These findings provide valuable insights into optimizing WAAM processing parameters and heat treatment strategies to enhance structural integrity and reliability. This work advances the understanding and application of additive manufacturing for producing high-performance aluminum alloys with tailored microstructures for demanding engineering applications.
