| 中文摘要: |
| 针对镁是密排六方结构,室温下塑性差，很难进行塑性成形，及塑性成形工艺中加热效率、生产效率等问题，通过对镁合金材料性能、模具结构、加工条件等进行研究并做实验分析，探究其加热成形工艺（以AZ21B镁合金成形电池壳为载体），进而获得较理想的塑性成形工艺方案及其模具。该工艺的主要创新在于设计并应用了一种镁合金加热送料通道，在保证生产效率的前提下，提高能量利用率，而且该工艺原料利用率高、制品综合力学性能好。 |
| 英文摘要: |
| In view of the difficulties of plastic forming at room temperature because of the close-packed hexagonal structure of magnesium，as well as the questions of heating efficiency，production efficiency and so on in the process of plastic forming，research and experimental analysis were made on the material property of magnesium alloys，mold structure，processing conditions and so on to explore the heating forming process（forming the battery shell with AZ21B magnesium alloy），a perfect scheme of plastic process and the mould were achieved. The main innovation of the process lies in the design and application of the heating and feeding channel of the magnesium alloy，ensuring the production efficiency and improving the energy utilization ratio. The process also has high raw material utilization and products have good comprehensive mechanics performance，which opens a new road for forming processing of magnesium alloys. |
