Abstract
Diffusion bonding is an effective way to join beryllium with other materials. To study the elements diffusion near the bonding interface so that improve the joints performance, the microstructure, and distribution of composition and phase on the interface of Be/00Cr17Ni14Mo2 stainless steel diffusion bonding were analyzed using scanning electron microscopy (SEM),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 results show that the elements diffuse mainly through the surface and the grain boundary, and the grain boundary is the main gateway of the elements diffusion. Dissimilar metal atoms gather first in the grain boundary and form intermetallic compounds, then the metal atoms diffuse through the grain boundaries or intermetallic compounds and the intermetallic compounds grow up on the crystal boundary, so the Be/00Cr17Ni14Mo2 stainless steel diffusion bonding joint is brittle fracture on the grain boundary.
