Fatigue Behavior Investigation of Uniaxially Prestrained Aluminum Alloy 2024‐T4.

The article explores the fatigue behavior of aluminum alloy 2024-T4 through uniaxial prestraining, focusing on dislocation development, fatigue life, and crack growth rate. Prestraining is found to enhance mechanical properties and fatigue crack threshold by increasing dislocation density and reducing particle-dislocation mismatch. The research sheds light on the mechanisms of dislocation development and their interaction with second-phase particles, emphasizing the significance of prestraining in enhancing the fatigue behavior of high-strength aluminum alloys. Additionally, the text includes studies on fatigue behavior and deformation of engineering materials, offering valuable insights into material science and engineering. [Extracted from the article]
