摘 要: 研究了冷变形对Cu-8～13Zn合金室温电阻的影响及其在退火过程中的恢复。结果发现：相同应变量所导致的电阻增量随Zn含量的增加而增加，在大应变量情况下(断面收缩率为60%～86%)，应变电阻增量与Zn含量基本成正比关系。应变电阻增量的54%在回复退火完成前得到恢复，并且恢复量与退火温度成正比关系，其余部分在再结晶过程中恢复。

Abstract:The influence of cold deformation on the resistivity of Cu-8～13Zn alloys and the resistivity restoring during annealing process were investigated. The results show that the strain resistivity increases with the increases of Zn content for the same cold deformation value. At a large deformation value (section shrinkage up to 60%～85%), the resistivity increment is proportional to Zn content on the whole. 54% of resistivity increment is restored during recovering annealing temperature, and the restoring ratio is proportional to annealing temperature. The rest is restored in the subsequent recrystallization process completely.
