Effects of Material Orientation and Degree of Deformation on the Tension–Compression Asymmetry of AA2024‒T4

The article delves into the intricate relationship between material orientation, deformation, and tension–compression asymmetry in AA2024‒T4, a widely used aluminum alloy in aerospace and automotive industries. It begins by highlighting the excellent properties of aluminum alloys and their critical role in protective structures subjected to impact and combined loading. The study focuses on understanding the yielding characteristics of materials, which is crucial for ensuring safety. Through a series of experiments and theoretical modeling, the authors investigate the plastic flow behavior, anisotropy, and hardening of AA2024‒T4 under various loading conditions. Notably, the research reveals that the tension–compression asymmetry is significantly influenced by material orientation and the degree of deformation. The article concludes with a discussion on the microscopic mechanisms behind this asymmetry and suggests future work to deepen the understanding of these phenomena.
