摘　　要：研究在不同退火温度下,Mn对冷轧Al-Mg-Si-Cu合金组织和性能的影响.通过绘制再结晶动力学曲线,测定不同Mn含量的Al-Mg-Si-Cu合金再结晶激活能和再结晶温度.实验结果表明,Mn可以有效的阻碍Al-Mg-Si-Cu合金再结晶行为.当w(Mn)<0.7%,Al-Mg-Si-Cu合金再结晶起始温度随Mn含量的增加而提高,再结晶结束温度不变.再结晶激活能随Mn含量的增加而提高.The effect of Mn addition on structures and properties of Al-Mg-Si-Cu alloy after cold-rolling at different annealed temperature was studied. Recrystallization temperature and activation energy of recrystallization was measured from the hardness-temperature curve. The results show that the addition of small amounts of Mn can inhibit the recrystallization. When the content of Mn is less than 0.7 wt%, the activation energy of recrystallization increases with the rising of Mn content, and Mn can boost the recrystallization beginning temperature.
