用测量硬度和电导率以及应用织构分析的方法研究了恢复和再结晶在冷轧 Al-4.5Mg—0.7Mn(AA5083)中的发展。为了研究这些参数对动力学和在变形、恢复及再结晶时织构演变的影响,在冷轧之前使用合理的预处理改变沉淀状态和初始织构。最后,把获得的结果与用传统法生产的材料进行了比较。

The development of recrystallization and recrystallization in cold-rolled Al-4.5Mg-0.7Mn (AA5083) was investigated by measuring hardness and conductivity and applying textural analysis. In order to study the influence of these parameters on the dynamics and the evolution of the texture during deformation, recovery and recrystallization, reasonable preconditioning was used to alter the sedimentation state and initial texture prior to cold rolling. Finally, the results obtained were compared with those produced by traditional methods.
