Abstract:Cu/Mo joints were prepared by melt infiltration technique and their boding properties were tested by static tensile test. Microstructure, chemical composition, and fracture morphology near the Cu/Mo interface were analyzed by optical microscopy(OM), X-ray dispersion spectrometer(EDS) and scanning electron microscopy(SEM), respectively. The results show that the joints fractured by means of fragile fracture and intergranular fracture at the side of Mo at the load of158 MPa, a diffusion region of Cu and Mo with the width of 0.2~1.0 μm formed in the interfacial region, and the atomic ratio of Cu and Mo in the diffusion region is about 1∶1.
