Research advances of magnesium and magnesium alloys worldwide in 2022.

• This review paper is aimed to summarize the latest important advances in cast magnesium alloys, wrought magnesium alloys, bio-magnesium alloys, Mg-based energy storage materials and corrosion and protection of Mg alloy in 2022, including both the development of new materials and the innovation of their processing technologies. • The main research focus of magnesium alloys were analyzed by bibliometrics. The bibliometric analyses indicate that the microstructure, mechanical properties, and corrosion of Mg alloys are still the main research focus. Bio-Mg materials, Mg ion batteries and hydrogen storage Mg materials have attracted much attention. • Based on the issues and challenges identified here, some future research directions are suggested. More than 4600 papers in the field of Mg and Mg alloys were published and indexed in the Web of Science (WoS) Core Collection database in 2022. The bibliometric analyses indicate that the microstructure, mechanical properties, and corrosion of Mg alloys are still the main research focus. Bio-Mg materials, Mg ion batteries and hydrogen storage Mg materials have attracted much attention. Notable contributions to the research and development of magnesium alloys were made by Chongqing University (>200 papers), Chinese Academy of Sciences, Shanghai Jiao Tong University, and Northeastern University (>100 papers) in China, Helmholtz Zentrum Hereon in Germany, Ohio State University in the USA, the University of Queensland in Australia, Kumanto University in Japan, and Seoul National University in Korea, University of Tehran in Iran, and National University of Singapore in Singapore, etc. This review is aimed to summarize the progress in the development of structural and functional Mg and Mg alloys in 2022. Based on the issues and challenges identified here, some future research directions are suggested. [ABSTRACT FROM AUTHOR]
