摘要
镁合金作为当前最轻的金属结构材料,由于其独特的优点被誉为"21世纪绿色工程材料"。介绍了超塑性特征;阐述了镁合金细晶超塑性的方法及机理;分析了不同晶粒细化工艺对镁合金微观组织和塑性变形性能的影响,最后展望了镁合金超塑性的发展方向。
Magnesium alloy is the lightest metal structure materials at present. Due to it's unique advantages, it is known as "green engineering materials of the 21st century". The characteristic of the superplasticity was introduced. The method and mechanism of fine grain superplasticity in magnesium alloys were expounded, and the effects of different grain refinement processes on the microstructure and plastic deformation properties of magnesium alloys were analyzed. Finally, the development direction of superplasticity of magnesium alloy was looked forward.
