Effect of Diffusion Heat Treatment on Thickness of Cold-Rolled Cu/Al Composite Laminate Interface

Abstract

The experiment has taken composite algorithm of cold rolling to prepare copper and aluminum composite laminate, studied the influence of diffusion heat treatment on the interface of copper and aluminum composite laminate. After Analyzed the relationship between the thickness of diffusion layer and diffusion heat treatment parameters, the experiments show that diffusion heat treatment temperature and diffusion time has influence on formation and size of the diffusion layer. At the same heat treatment temperature, the thickness of diffusion layer has parabolic relation with diffusion time with diffusion time extending and thickness of diffusion layer increasing. And the thickness of diffusion layer is increasing at the same heat treatment time. And the thickness of diffusion layer has exponential relation with diffusion heat treatment temperature. Quantitative analyzed the relationship between diffusion heat treatment parameters and diffusion layer thickness, and established a formula to describe the interface thickness and diffusion of heat treatment temperature and time.
