介紹了鎂合金在單軸壓縮、單軸拉伸、軋制和擠壓條件下塑性變形的力學行為及微觀組織結構演變規律。簡述了鎂合金中二次拉伸孿生現象以及各種變形條件下孿生與孿生變體類型的選擇規律。基于對鎂合金位錯滑移、機械孿生及動態回復與再結晶行為的認識，對鎂合金力學行為的各向異性、軋制與擠壓成型能力的影響規律進行了探討，強調了初始織構對變形機制、動態再結晶及成型能力的重要影響。最后討論了析出強化鎂合金塑性變形與強韌化機理。
- Abstract:
-
Mechanical behavior and microstructure evolution of Mg alloys during compression, tension, rolling and extrusion were reviewed. Different types of twinning and twin variants formed in Mg alloys under different deformation conditions, especially double extension twins, were reported. Based on the understandings of dislocation slip, mechanical twinning and dynamic recovery and recrystallization, mechanisms of mechanical property anisotropy, rolling and extrusion workability were discussed. The effect of initial texture on deformation mechanisms, dynamic recrystallization and workability was stressed. Plastic deformation and strengthening mechanism of precipitation strengthened Mg alloy were also discussed.
