A Critical Review on Improving the Fatigue Life and Corrosion Properties of Magnesium Alloys via the Technique of Adding Different Elements

Magnesium is the eighth-most abundant element in world and its alloys have a widespread application various industries such as electronic transport (i.e., air, land, sea) engineering, due to their significant mechanical properties, excellent machinability, high strength weight ratios, low cost. Although monolithic Mg metal known lightest industrial (magnesium density 30% less than of aluminum, this unique property increases attractiveness usage transportation industry), one limitations magnesium, which affects on applications industries, very reactivity with an electronegativity 31.1 can give electrons almost all metals corrodes quickly). To overcome problem, scholars are trying produce magnesium (Mg) that more resistant variety loads environmental conditions. In regard, include well-known materials aluminum (Al), Zinc (Zn), Manganese (Mn), Silicon (Si), Copper (Cu), etc., amount directly properties final products. present review paper, authors attempted latest achievements, methods, influential factors (finish-rolling, pore defects, pH value, microstructure, manufacturing processes, etc.) fatigue life corrosion resistance most alloys, including AM50, AM60, AZ31, AZ61, AZ80, AZ91, ZK60, WE43, under The summarized results practical hints presented paper be useful enhance reliability quality Mg-made structures.
