阐述了镁合金应变硬化行为的研究现状；概括了组织参数对镁合金应变硬化行为的影响；提出此研究领域尚需解决的科学问题。镁合金的应变硬化行为与激活变形模式的类型和数量有密切的关系。此外，织构、固溶元素、析出相和晶粒尺寸等组织参数对滑移和孪生主导变形的应变硬化行为都有较大的影响。目前，组织参数与应变硬化行为的关系还需要更加系统的研究。此外，有必要研究和开发适用于镁合金的应变硬化理论模型。

Some aspects of the present research on the strain hardening behavior at room temperature in wrought magnesium alloys were reviewed. The influence of the typical microstructure parameters on the strain hardening behavior of magnesium alloys was also discussed. Finally, a few critical scientific problems in this research field were pointed out. The strain hardening behavior of magnesium alloys exhibited a strong dependence on the type and amount of active deformation modes. Moreover, both the strain hardening behavior dominated by dislocation slip and twinning can be greatly influenced by texture, solid solution element, precipitate and grain size. Currently, the relationship between the microstructure and strain hardening behavior has not been symmetrically studied. Furthermore, further works are needed to study and develop the strain hardening model suitable for magnesium alloys.
