Research progress on wrought magnesium alloys with strength-ductility synergy and their microstructural control
Wrought magnesium alloys have competitive comprehensive mechanical properties after plastic deformation.However,the industrial application of wrought magnesium alloys is limited by their strength-ductility incongruity.In general,the enhancement of strength and ductility can be achieved synchronously with the improvement of microstructure through alloying design and the optimization of plasticity processing.The latest typical research progress of wrought magnesium alloys with strength-ductility synergy was reviewed in this paper.These alloys are classified into three categories of high-strength,medium strength-ductility and ultra-high ductility based on their properties and the microstructural control methods to realize strength-ductility synergy instead of trade-off coordination,is further elaborated,including alloying,refining grain,modifying the second phase and precipitate,texture control and forming heterogeneous structure.Ultimately,some noteworthy issues about the development of strength-ductility synergistic wrought magnesium alloys and their microstructural control methods have been summarized.
