We develop a methodology to calculate the electrochemical potentials of intermetallic compounds and alloys using a simple model based on the Born-Haber cycle. Calculated electrochemical potentials are used to predict and control the formation of galvanic cells and minimize corrosion. We demonstrate the applicability of our model by minimizing galvanic corrosion in Mg-3wt%Sr-xZn alloy by tailoring the Zn composition. The methodology proposed in this work is applicable for any general alloy system and will facilitate efficient design of corrosion resistant alloys. ？ 2021 English National Engineering Research Center for Magnesium Alloys of China, Chongqing University Computational design of Mg alloys with minimal galvanic corrosion Article 10.1016/j.jma.2021.06.019 1 Journal of Magnesium and Alloys, v.10, no.7, pp.1972 - 1980 Journal of Magnesium and Alloys 10 7 1972 1980 Y scie scopus 000844456000001 2-s2.0-85111604161 Metallurgy & Metallurgical Engineering Metallurgy & Metallurgical Engineering Article MECHANICAL-PROPERTIES MAGNESIUM ALLOYS BIOMATERIALS BEHAVIOR Cluster expansion First-principles Galvanic corrosion Magnesium Alloys Modeling Thermodynamics
