Diffusion Bonding of Fe-based Amorphous Ribbon to Crystalline Cu
A copper rod/FeSiB amorphous ribbon/copper rod sandwich laminated composite material has been successfully fabricated by co-pressing at temperatures within supercooled liquid region.The bonding interface has been characterized by scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HRTEM).Results showed that a good bonding interface could be obtained only when the initial surface were carefully polished.The diffusion zone confirmed by EDS is about 60nm,indicating the bonding is in atomic metallurgical level via limited diffusion.The present results show that even the diffusion length is very small,diffusion bonding in the supercooled liquid region could be an effective way for fabricating Fe-based metallic glass/Cu laminated composites.
