Abstract
Magnesium alloys have low density,high specific strength,and good damping performance,and are widely used in aerospace,transportation,and other fields.However,their flammability restricts further development.This paper reviews the research progress on the flame retardant properties of magnesium alloys with rare earth alloying,systematically analyses the flame retardant mechanisms of rare earth elements,and summarizes the research progress of flame retardant magnesium alloys with single and mixed rare earth alloying.Meanwhlie,it also points out existing issues such as high cost and unclear dynamic mechanisms.Finally,future research directions are envisaged,such as multi-scale structural adjustment and the synergistic alloying design of mixed rare earths,to promote the efficient development and application of flame retardant magnesium alloys.关键词
