针对电缆带以铝节铜的市场需求和超薄铜铝复合板带制备技术缺乏的现状，提出了包含叠轧的多道次累积轧制复合工艺，同时采用快速在线退火工艺成功制备了厚度为0．12 mm的超薄铜铝复合电缆带，并对其不同道次和不同退火工艺下的拉伸力学性能进行了分析．研究表明：采用高温短时在线热处理可以达到低温长时退火处理的效果；超薄铜铝复合带的力学性能对厚度特别敏感；改变初始坯料状态和降低中间退火温度可以改善最终复合带的力学性能．
According to the market demand of Cu/Al bimetal instead of pure Cu for coax strip and the lack of manufacturing technology for ultra-thin Cu/Al clad strip. Multi-cycles accumulative roll bonding was proposed, and using rapid online annealing process, the ultra-thin Cu/Al clad strip with 0.12 mm thick was successfully fabricated. Its mechanical property at different cycles and annealing process was analyzed, and the results indicate that, using high temperature and short time online annealing process can reach the same effect of low temperature and long time. The mechanical property of Cu/Al clad strip with 0.12 mm thick is very sensitive to its thickness. Changing the original condition of materials and decreasing annealing temperature among different cycles can improve the mechanical property of Cu/Al clad strip.
