Summary: | Cu/Fe multilayered laminated composite was fabricated by a repeated diffusion-rolling procedure. With diffusion bonding initially, thinner layer was fabricated by rolling, and this procedure was repeated. The evolution of structure and properties of Cu/Fe multilayered composite was investigated. The low inter-solubility interface was examined by using high angle annular dark field (HAADF) imaging mode in scanning transmission electron microscopy (STEM). The interfacial strength of Cu/Fe was enhanced by the plastic deformation after rolling. Parallelism of interfaces can almost be achieved when the thickness of layer is above 25 mu m or total reduction ratio is lesser than 99%. An inter diffusion area with about 25nm in width was present at the interface. HR-TEM and FFT investigations at the interface region revealed that disordered substitutional solid solution of Cu and Fe occurred during the procedure. |
