This study investigates the distribution of residual stresses and microstructural changes in aluminum 6061 alloy induced by the wire drawing process. To obtain the material properties necessary for the simulation, mechanical properties of aluminum 6061 were acquired through uniaxial tensile testing, and the Swift model was employed as the constitutive equation. The finite element analysis revealed the distribution of residual stresses, indicating the formation of compressive residual stresses at the center and tensile residual stresses at the surface. The analysis confirmed that the reduction in area plays a critical role in the residual stress distribution, emphasizing that a higher reduction in area is essential for alleviating tensile residual stresses at the surface. Additionally, microstructural analysis demonstrated a refinement of grain structure resulting from substantial plastic deformation, which contributed to an increase in both yield strength and tensile strength. These findings indicate that achieving a higher reduction in area is crucial for minimizing residual stresses and attaining desirable mechanical properties in aluminum wire drawing processes.
