| 目的 研究不同含量Zn元素对镁合金塑性、强度的改良效果。方法 以Mg-Al-Ca-Mn合金为基础，采用热挤压成形加工方法，分析不同Zn含量对其显微组织和力学性能的影响。结果 Zn元素可以改变挤压态镁合金的显微组织，对其主合金相影响不大，但可以改变衍射峰强度。Zn元素可以提高挤压态镁合金的屈服强度和伸长率，提高镁合金韧性;ACMZ2合金综合性能最佳。结论 热挤压成形能够细化镁合金晶粒，Zn元素含量可以改善镁合金微观组织和力学性能，可在实际生产中根据需求调整Zn元素含量以获得最佳性能。 |

| In order to study the improvement effect of different Zn content on the plasticity and strength of magnesium alloy, the influence of different Zn content on the microstructure and mechanical properties of Mg-Al-Ca-Mn alloy is analyzed by hot extrusion process. The results show that Zn element can change the microstructure of extruded Mg alloy. It has little effect on the main alloy phase, but it can change the diffraction peak intensity. Zn element can improve the yield strength and elongation of extruded magnesium alloy, and improve the toughness of magnesium alloy. ACMZ2 alloy has the best comprehensive properties. Hot extrusion can refine the grain size of magnesium alloy, and Zn content can improve the microstructure and mechanical properties of magnesium alloy. Therefore, the content of Zn element can be adjusted according to the demand in actual production to obtain the best performance. |
