| Abstract: | Influence of pre-deformation process on twinning behavior of magnesium alloys was analyzed, the precipitation behavior of different types of magnesium alloys under pre-deformation and aging treatment was discussed, and the change law and strengthening mechanism of mechanical properties of the magnesium alloys under this process was elucidated, and the precipitation behavior of magnesium alloys could be regulated through pre-deformation process was put forward, so that the intragranular structure of the magnesium alloys could develop towards a structure conducive to improving mechanical properties. Finally, the future research direction of pre-deformation and aging treatment process was prospected. |
