| 中文摘要: |
| 细化镁合金的晶粒可极大改善其综合力学性能，单一的细化方法包括在熔体中施加外力场作用、高压和激冷作用以及大塑性变形，单一细化方法下的材料性能难以满足实际需求，且生产效率低、成本高、质量难以保证。2种及以上细化晶粒方法的结合可以实现镁合金性能的极大提升，通过评述镁合金复合加工方法，包括挤压铸造-固态挤压成形、挤压铸造-正挤压成形、FE-CCAE复合变形工艺、电磁脉冲结合轧制工艺、超声振动-挤压加工等，详细阐述镁合金复合细晶强化工艺的研究进展，为进一步研究和开发更加高效绿色的镁合金晶粒细化复合成形技术提供参考。 |
| 英文摘要: |
| The grain refinement of magnesium alloy can greatly improve the comprehensive mechanical properties. Single refinement method includes applying external force field, high pressure and chilling action, and large plastic deformation in melt. The properties of materials processed by single refinement method are difficult to meet the actual production needs, and the production efficiency is low, the cost is high, and the quality is difficult to guarantee. The combination of two or more grain refinement methods can achieve greater improvement in the properties of magnesium alloys. Through the review on composite processing methods of magnesium alloy, including squeeze casting-solid extrusion forming, squeeze casting-positive extrusion, FE-CCAE composite deformation process, electromagnetic pulse combined rolling process, ultrasonic vibration-extrusion processing, et al, the research progress on composite refinement strengthening process of magnesium alloy is expounded in detail, which provides a reference for further research and development of more efficient and green composite forming technology of refining magnesium alloy grains. |
