摘要：

WS (Weathering steel) is of great significance in addressing corrosion challenges. Compared with traditional structural steel, it exhibits excellent corrosion resistance. This paper aims to investigate the corrosion behavior and mechanical properties of Q450 WS in a corrosive environment and evaluate the corrosion resistance of WS under different corrosion loss rates and different corrosion times. The study includes 3D scanning, hardness testing, uniaxial tensile testing, and nanoindentation testing. Firstly, sulfuric acid immersion tests were conducted on Q450 WS, with Q450 HS (high-strength steel) serving as the control group. Subsequently, uniaxial tensile and nanoindentation tests were conducted on both types of steel before and after corrosion. Stress–strain curves and force–displacement curves under various conditions were obtained to analyze the effect of corrosion on their mechanical properties and to evaluate its overall impact. Then, the specimens were subjected to 3D scanning and hardness testing, generating 3D surface profiles and cross-sectional height difference maps, which facilitated a more in-depth understanding of the corrosion effects. Finally, a revised Johnson–Cook constitutive model was proposed, and its predictive accuracy and reliability were validated through comparison with the experimental results. © 2025 Elsevier Ltd
