Abstract Effect of calcium (Ca) addition in a novel magnesium (Mg) alloy including zinc, aluminum, and manganese from multimodal approaches was investigated to achieve a high strength and low corrosion rate material. Tensile and compression tests were carried out to measure the mechanical properties and precise analysis such as hydrogen evolution, weight loss, electro-chemical and scanning kelvin probe force microscopy to realize the corrosion behavior of the prepared Mg alloy. Ca addition had a significant effect in the ultimate strength of the alloy through second phase formation, effective grain refinement, and texture strengthening. However, it decreased the corrosion rate after long immersion time due to the secondary phase formation. Furthermore, low Ca content can be incorporated in the alloy because of the solubility limit of Ca in the matrix, which slightly increases the corrosion rate adjusting the optimum values of both strength and corrosion resistance.
