In present study, micro-alloyed extruded Mg0.5Zn0.2Ca and Mg0.5Zn0.2Ge alloys were developed to avoid the severe galvanic corrosion between Mg matrix and second phases. Corrosion behavior, mechanical integrity and fatigue behavior in two corrosive electrolytes of these two alloys were investigated. The results revealed a better short-term corrosion property for Mg0.5Zn0.2Ge alloy, but an improved long-term corrosion resistance for Mg0.5Zn0.2Ca alloy, resulting from the different protective abilities of surface layers and microstructures of the alloys. Although Mg0.5Zn0.2Ca alloy presented relatively lower strength owing to the weaker texture, it owned better mechanical integrity than Mg0.5Zn0.2Ge alloy due to the more uniform corrosion in salt spray, indicating the significant effect of localized corrosion on mechanical integrity of materials. Furthermore, the corrosion of the alloys in electrolytes decreased the fatigue resistance for both alloys, but Mg0.5Zn0.2Ca showed higher sensitivity to corrosive environments under cyclic loading. The comprehensive studies of these two alloys highlight the interactions between corrosion and mechanical integrity and/or fatigue behavior of materials and suggest the importance of the investigation of the overall properties when new Mg alloys are developed and evaluated for practical applications.}, note = {Online available at: \url{https://doi.org/10.1016/j.matdes.2019.108285} (DOI).
