摘要
简述了镁合金晶体结构在其低温变形协调机制方面的局限性。从晶粒取向和尺寸角度分析探讨了轧制镁合金的塑性变形协调机制。综合评述了镁合金从低温到高温轧制变形时不同协调机制下微观组织形成机理。最后对提高镁合金低温塑性的前景提出了展望。
The limitations of the crystal structure of magnesium alloy in its coordination mechanism of low temperature deformation were briefly described.The plastic deformation coordination mechanism of rolled magnesium alloy was discussed from grain orientation and size.The microstructure formation mechanism of the magnesium alloy under different coordination mechanisms during rolling deformation from low temperature to high temperature was synthetically reviewed.Finally,the prospect of improving the low temperature plasticity of magnesium alloys was put forward.
