铜/钢/铜冷轧复合薄带弯曲性能实验研究
|
摘要
以Q345钢带为基材,T3纯铜为覆材,通过冷轧复合—中间退火—冷轧减薄—轧后退火的工艺路线,制备出铜/钢/铜复合薄带.通过反复弯曲实验研究复合带厚度和退火温度对复合带弯曲性能的影响.实验发现:复合带的弯曲性能主要依赖于冷轧复合中的机械作用以及退火过程中的扩散作用.冷轧复合带随着厚度逐渐减薄,弯曲性能近似线性增强.退火工艺能大幅度提高复合带的弯曲性能,退火温度与弯曲性能基本呈指数关系变化.
Using Q345 steel strip as the matrix and T3 pure copper as cladding material,a copper/steel/copper composite strip can be produced by a process route of cold-rolled composing-intermediate annealing-cold-rolled thinning-post rolling. The effects of the strip thickness and annealing temperature on the bending capacity of the composite strip were investigated by repeated bending experiments. It is found that the bending capacity of the composite strip mainly depends on mechanical interaction during the cold-rolled composing and the diffusion features during annealing. When the strip thickness becomes thinner during rolling,the bending capacity of the cold-rolled strip almost linearly increases. Moreover,the annealing process improves the bending capacity of the strip as well. The results shows that the bending capacity has an exponential relationship with annealing temperature.
