“…The fatigue life of aluminum alloys is sensitive to the loading path, and the load path sensitivity is influenced by a number of factors, such as the material properties, loading conditions, and microstructure. [12][13][14][15] Already in 1970, Miller et al 16 called attention to the effect of strain rate on the cyclic behavior of materials, emphasizing the need for further research on the cyclic stress-strain curve. Woodthorpe et al 17 Many authors have studied the cyclic behavior of aluminum alloys under various conditions such as heat treatments, anisotropy, strain rate, mean strain, and squeeze casting in stress control tests.…”

The focus of this study is to investigate the impact of cyclic loading path and temperature on the mechanical behavior of AA2024 aluminum alloy, a material commonly used in the aerospace industry. Our study aims to understand the cyclic evolution of work hardening (isotropic and kinematic) in response to different loading paths: tension‐compression cycles followed by equivalent torsion cycles, and vice versa. We also perform microstructural investigations using a scanning electron microscope (SEM) to gain insights into the evolution of fatigue damage during cyclic loading. By examining these factors, we aim to provide insights into the material's mechanical behavior and anisotropy. This research contributes to improving our understanding of the performance of AA2024 alloy under cyclic loading conditions.

While research on lightweight materials has been carried out for decades, it has become intensified with recent climate action initiatives leading pathways to net zero. Aluminum alloys are at the pinnacle of the light metal world, especially in the automotive and aerospace industries. This review intends to highlight recent developments in the processing, structure, and mechanical properties of structural Al-Si alloys to solve various pressing environmental issues via lightweighting strategies. With the excellent castability of Al-Si alloys, advancements in emerging casting methods and additive manufacturing processes have been summarized in relation to varying chemical compositions. Improvements in thermal stability and electrical conductivity, along with superior mechanical strength and fatigue resistance, are analyzed for advanced Al-Si alloys with the addition of other alloying elements. The role of Si morphology modification, along with particle distribution, size, and precipitation sequencing, is discussed in connection with the improvement of static and dynamic mechanical properties of the alloys. The physics-based damage mechanisms of fatigue failure under high-cycle and low-cycle fatigue loading are further elaborated for Al-Si alloys. The defect, porosity, and surface topography related to manufacturing processes and chemical compositions are also reviewed. Based on the gaps identified here, future research directions are suggested, including the usage of computational modeling of microstructures and the integration of artificial intelligence to produce mass-efficient and cost-effective solutions for the manufacturing of Al-Si alloys.
