This paper presents a hybrid two dimensional Dual Reciprocity Boundary Element Method (DRBEM) for modelling the primary reactions of iron corrosion in an acidic solution. The main focus is on the establishment of the DRBEM approach for this kind of problems in which the mathematical formulation is based on the Planck-Nerst law, the conservation of charge and the conservation of mass for the species participating in the process. The model is capable to describe the transport process of Fe +2 and H + ions in the aqueous electrolyte driven by the instantaneous electric field that results from the existent charge distribution. The results of this work compare qualitatively well with previously established references.

Dual-phase (DP) steels are produced from a specific heat treatment procedure and have recently emerged as a potential class of engineering materials for a number of structural and automobile applications. Such steels have high strength-to-weight ratio and reasonable formability. The present study aims to investigate the effects of four different and conventional heat treatments (i.e., hot rolling, normalizing, annealing, and intercritical annealing) on the resulting microstructural patterns and on the electrochemical corrosion behavior. Electrochemical impedance spectroscopy (EIS) and Tafel plots were carried out on heat treated steel samples in a 0.5 M NaCl solution at 25 8C with neutral pH. An equivalent circuit analysis was also used to provide quantitative support for the discussions. The normalizing and the annealing heat treatments have provided the highest and the lowest corrosion resistances, respectively. The intercritical annealing and as-received (hot rolled) low carbon steel samples have shown similar corrosion behavior. Although a deleterious effect on the corrosion resistance has been verified for DP steel due to the residual stress from the martensite formation, it combines good mechanical properties with intermediate electrochemical corrosion resistance.
