Description:
Materials, Vol. 11, Pages 1432: Model for the Correlation between Anodic Dissolution Resistance and Crystallographic Texture in Pipeline Steels Materials doi: 10.3390/ma11081432 Authors: Manuel Madrigal-Cano Luis Hernández-Maya José Manuel Hallen Mónica Corrales-Luna Elsa Miriam Arce-Estrada Tu Le Manh This paper presents a novel physical–mathematical model to describe the relationship between the crystallographic texture and corrosion behavior of American petroleum institute (API) 5L steels. Symmetric spherical harmonic functions were used to estimate the material’s corrosion resistance from crystallographic texture measurements. The predictions of the average corrosion resistance index made from the crystallographic texture were in good agreement with those obtained from potentiodynamic polarization and electrochemical impedance spectroscopy measurements for the studied steels. This agreement validates the capacity of this model and opens the possibility of applying it as a novel criterion for materials selection and design stages to combat corrosion problems.
