摘      要：Magnesium alloys have received considerable research interest due to their lightweight,high specific strength and excellent ***,their plastic deformation is more complicated compared to cubic materials,primarily because their low-symmetry hexagonal closepacked(hcp) crystal *** twinning is a crucial plastic deformation mechanism in magnesium,and twins can affect the evolution of microstructure by interacting with other lattice defects,thereby affecting the mechanical *** paper provides a review of the interactions between deformation twins and lattice defects,such as solute atoms,dislocations and twins,in magnesium and its *** review starts with interactions between twin boundaries and substitutional solutes like yttrium,zinc,silver,as well as interstitial solutes like hydrogen and *** is followed by twin-dislocation interactions,which mainly involve those between {10■2} tension or {10■1} compression twins and , or type *** following section examines twin-twin interactions,which occur either among the six variants of the same {10■2} or {10■1} twin,or between different types of *** resulting structures,including twin-twin junctions or boundaries,tension-tension double twin,and compression-tension double twin,are discussed in ***,this review highlights the remaining research issues concerning the interactions between twins and lattice defects in magnesium,and provides suggestions for future work in this area.
