微量合金元素对压延铜箔组织及挠曲性能的影响
Microstructure and Flexural Properties of Calendered Copper Foil with Addition of Trace Alloying Elements
摘要
Abstract
In order to meet the needs of high deflection properties of calended copper foil,C1100 copper strip with Ag,Sn,In,B,O and other elements was rolled by semi-continuous casting process at different pass rates.The effects of composition and pass rate on grain size,grain orientation,deflection properties and mechanical properties of calended copper foil were studied and analyzed.The results showed that the flexural properties of rolled copper foil were closely related to grain size and grain orientation,and were positively corre-lated with the proportion of texture(100).When the element content(Ag,Sn,In,B)/O was 0.55~1.09,the maximum grain size,(100)texture ratio and flexion times of copper foil increased first and then decreased.The tensile strength showed a cross trend and the elon-gation showed a strong negative trend.When the element content was 0.71,the maximum number of flexure times was 53,000.In order to further improve the flexural properties of rolled copper foil,the process of pass processing rate was optimized.The maximum grain size,(100)texture proportion and flexural times increased as they decreased,and reached the best at an average pass processing rate of 8.89%,with(100)texture proportion of 92.5%and the flexural times of 120,000,which were significantly better than the properties of existing copper foil on the market.关键词
