| Abstract: | In this paper the research and development status of wrought magnesium alloy containing rare earth elements are reviewed. The effects and influence of rare earth on the microstructure, mechanical properties and deformability of wrought magnesium alloys are analyzed. The formation, effects and properties of quasicrystal phase in wrought magnesium alloys containing rare earth are summarized. The problems and difficulties in the present work are discussed. It is considered that wrought magnesium alloy containing rare earth is an important developing direction in exploitation and application of wrought magnesium alloys. |
