对工业用A4纯铝进行拉拔和轧制两种塑性变形,研究了纯铝导线材料的微观结构演化、强度和导电率。结果表明:在变形量较小时拉拔变形和轧制变形后纯铝铝导线主要由拉长晶粒组成,这些拉长晶粒由位错亚结构组成的小角晶界组成;在相近的等效应变变形情况下,轧制样品中高角晶界的比例更高。拉拔变形后样品的强度和塑性均优于轧制变形后的样品。拉拔变形使材料具有更高强度和导电率。探讨了材料的导电性与形变强化间的关系。 |

Commercial A4 pure aluminum electrical wire was subjected to cold drawing and cold rolling respectively, and then their microstructure, strength and electrical conductivity were investigated systematically. Results show that in the case of less deformation, the microstructure both of the cold drawn and rolled aluminum electrical wires consists of elongated grains with low-angle grain boundaries and dislocation substructures; In case of similar equivalent strain deformation, there exists higher percentage of high- angle grain boundaries in the cold- rolled wires. While the strength and ductility of the cold drawn wires are higher than that of the cold rolled ones. Finally, the relationship between deformation strengthening and conductivity of the pure aluminum was elucidated. |
