Abstract:Magnesium alloys as potential lightweight structural material in the transportation field have low density, high specific strength and specific stiffness. However, the poor high-temperature oxidation resistance and flammability of magnesium alloys limit their application. This article described the basic principles of high-temperature oxidation and combustion of magnesium alloys in the air, and the influencing factors of high-temperature oxidation in detail. The research progresses of high temperature oxidation and ignition resistance of magnesium alloys were summarized, including the oxidation resistance model theory and the flame retardant mechanism alloying with elements such as Ca, be, Sr, rare earth elements, etc. Some problems encountered in the development of flame retardant magnesium alloys were put forward and the possible development directions were pointed out.
Key words: magnesium alloy; composition; microstructure; high temperature oxidation; ignition resistance
