The microstructure of joint, behavior of atom mutual diffusion and distributions of alloy elements within the joint were analysed. The shearing strength of joints was tested using a special tester. The experimental results show that the Cu-based microcrystalline braze performs an excellent wettability and spreadability during vacuum brazing of 25Cr3MoA/YG6, and the brazing seam obtained is permeated soundly, thus the joint has a higher welding-on rate; the microstructure of brazing seam consists mainly of Cu-rich Cu13.7Sn phase and Ni-rich Cu9NiSn3 phase distributing within the Cu-rich phase. The diffusion range of Cu atoms from brazing seam to base metals reaches to 2.5μm. Therefore, the diffusion brazing of 25Cr3MoA and YG6 has be realized and the shearing strength of joint is high up to 169MPa.
