摘要

采用金相显微镜、SEM及EDS等分析手段对Cu/Al冷轧复合界面结合机理进行研究

建立扩散退火阶段不同轧制压下率时的扩散层生长动力学方程

并探讨了不同压下率对界面扩散层生长的影响。结果表明

轧制复合阶段界面形成激活中心数量随压下率的升高而增加

当压下率为75%时达到峰值。另外

压下率在退火温度较高时对扩散层生长影响显著。

Abstract

Bonding mechanism of cold rolling Cu cladding Al Compound was analyzed by OM （optical microscope） and SEM （scanning electron microscope） as well as EDS （energy dispersive spectrometer）. Growth dynamic equation of diffusion layer of the interface at different rolling reduction with annealing treatment was established to understand effects of different reduction on growth rate of diffusion layer. The results show that with increasing in reduction

numbers of activated center formed at the interface are increased during rolling compound

and maximum value can be observed with 75% reduction. In addition

in the condition of the higher annealing temperature

reduction is greatly related to the growth rate of diffusion layer.
