Notes:
By means of optical microscope(OM), scanning electron microscope(SEM), X-raydiffraction(XRD) and shear test, the microstructure and mechanical property of 1Cr18Ni9Ti stainlesssteel brazed joints with BNi-2 filler by electron beam brazing(EBB) and vacuum brazing(VB) areinvestigated respectively. The results show that, the microstructures of brazed joint with BNi-2 byEBB are mainly solid solutions of Ni. And the microstructures of brazed joint by VB are composed oftwo parts: one part is a solid solution of Ni, which lies adjacent to base metal; another part is chemicalcompound structures present in the centre zone of brazing seam. The shear strength of brazed joint byEBB is higher than that of by VB. This is closely related with the microstructures of brazed joint
