英文摘要Face-centered cubic (FCC) metals are widely used in the field of structural materials due to their excellent mechanical properties, and their fatigue behaviors have always been a focus of attention. Herein, 1060 aluminum alloys with different processing states and copper are selected to study the high cycle fatigue performance at room temperature and high temperature. The fracture morphology and dislocation evolution are characterized through characterization methods such as scanning electron microscope and transmission electron microscope. Based on the research, the main movement mode of dislocations (plane slip or wavy slip) are influenced by stacking fault energy (SFE), which further has a significant impact on fatigue performance. When the SFE of the FCC metal is higher, wavy slip dominates and the material is sensitive to temperature changes; on the contrary, during cyclic loadings, metal with lower SFE is dominated by plane slip, due to the reversibility of plane slip, the damage to the material with low SFE under fatigue loading is more uniform. For face-centered cubic (FCC) metals with low stacking fault energy (SFE), the movement of dislocations is dominated by planar slip. Under the situation of higher energy inputs, dislocations gradually adjust from disorder to ordered dislocation configurations; for FCC metals with very high SFE, the plastic deformation of the material is controlled by wavy slip.image (c) 2024 WILEY-VCH GmbH
