3D morphology reconstruction-based modelling and mechanical degradation study of corroded low alloy steel specimens
Highlights Morphology evolution characters of corroded low alloy steel were extracted. 3D morphology reconstruction-based model for corroded steel specimen was developed. Effects of corroded rough morphology were revealed and quantitatively analysed. Prediction equations for corroded steel were put forward to describe the nominal material properties.
Abstract The evolution law in surface morphology of low alloy steel after corrosion was investigated through accelerated corrosion test in this paper. Specimens with varying corroded levels were parametrically reconstructed based on their fractal features. The influence of morphology on mechanical degradation was quantified based on uniaxial tensile simulation, and the accuracy was assessed by comparison with existing tests and methods. The analysis results indicate that the morphology of corroded steel has significant additional adverse effects on its nominal mechanical properties and can reach 15% maximum on yield strength, which cannot be reflected by traditional methods that only consider corrosion-induced section reduction.
