摘要

This study systematically investigates the influence of two-dimensional ultrasonic vibration-assisted incremental forming (2D-UVIF) on the surface integrity and mechanical properties of 5052 aluminum alloy. The proposed method addresses the limitations of conventional single-point incremental forming (SPIF), such as poor surface quality, high forming force, and limited forming depth, by integrating multi-directional ultrasonic vibration into the forming process. A specialized 2D-UVIF apparatus was developed, and experimental studies were conducted through micro-hardness testing, x-ray analysis, and scanning electron microscopy (SEM) to evaluate surface characteristics and fracture morphology. The results demonstrate that 2D-UVIF significantly enhances surface finish, reducing roughness by over 50% compared with SPIF, while simultaneously improving hardness by approximately 44.14% with greater uniformity. In addition, 2D-UVIF contributes to more stable residual stress distribution and promotes refined micro-void networks on fracture surfaces, indicating improved toughness and resistance to crack initiation. These findings confirm that the synergistic effects of multi-directional ultrasonic vibration not only optimize mechanical performance but also markedly improve surface integrity, making 2D-UVIF a promising advanced forming technology for thin-walled aluminum alloy components in aerospace, automotive, and marine applications.
