| 中文摘要: |
| 镁合金具有低密度、高比刚度和高比强度的优点，但其延展性不足及较差的耐腐蚀性严重阻碍了其大规模应用。研究者采用各种技术开发了多种镁基复合材料，开发出的镁基复合材料具有低密度、高强度及良好的耐腐蚀性能。综述了制备镁基复合材料的主流技术及制备的复合材料性能，分析了各种制备技术的优缺点。制备技术包括搅拌铸造、挤压铸造、超声波辅助铸造、等离子喷涂等液相制备技术，以及冷喷涂、粉末冶金、高压扭转和搅拌摩擦加工等固相制备技术。 |
| 英文摘要: |
| Magnesium alloys have the advantages of low density, high specific stiffness, and high specific strength, but their lack of ductility and poor corrosion resistance seriously hinder their large-scale application. To overcome these problems, researchers have developed various magnesium matrix composites using various technologies. The magnesium matrix composites developed have low density, high strength and good corrosion resistance. This paper presents an overview of the main techniques used to prepare magnesium matrix composites and the properties of the composites prepared. The liquid-phase preparation techniques include stir casting, squeeze casting, ultrasonic assisted casting, plasma-spraying, and the solid-phase preparation techniques include cold spraying, powder metallurgy, high-pressure torsion and friction stir processing. This paper provides a brief overview of the advantages and disadvantages of the preparation techniques. |
