Eivani, A.R. (author), Mehdizade, M. (author), Chabok, S. (author), Zhou, J. (author)Magnesium alloys have many unique properties, mostly benefitting from the low density of magnesium. However, they are not competitive, when compared with other lightweight materials, such as aluminum alloys, particularly in ductility and corrosion resistance. There is a strong need to improve the mechanical properties and corrosion resistance...journal article 2021
