Diffusion bonding is an effective way to join beryllium with other materials. To study the elements diffusion on the bonding interface to improve the joints performance, the microstructure, and the distribution of composition and phase on the interface of Be/Cu/00Cr17Ni14Mo2 stainless steel diffusion bonding were analyzed using scanning electron microscopy (SEM), energy dispersive spectrometer (EDS), scanning auger microscopy (SAM), x-ray diffraction (XRD), and the elements diffusion on the interface and the relationship between phases distribution and microstructure were also discussed. The result show that the original interface of Be/Cu diffusion bonding is the most weak site of the whole diffusion bonding zone and the fracture site of specimen. Dissimilar metal atoms gather first in the grain boundary and form intermetallic compounds, and the grain boundary or intermetallic compounds are the main gateway of the elements diffusion. The copper interlayer has greatly hindered the interdiffusion between stainless steel elements and beryllium, so the formation of intermetallic compounds between beryllium and stainless steel elements are avoided effectively to improve the diffusion bonding joints strength.
