摘要：
The interfacial microstructure and joining properties of titanium-zirconium-molybdenum (TZM) alloy joints were characterized by SEM, EDS, XRD, mechanical tests, etc. The results show that the Ni-Ti brazing filler metal can efficiently realize the high-temperature vacuum brazing of TZM. Mo in the base metal and Ni in the braze filler metal form MoNi4 phase, which is the main reason for the metallurgical bond between the TZM and the Ni-13.7Ti/TZM interface region. Ti in Ni-44Ti braze filler metal dissolves in Mo to form an infinite solid solution in TZM/Ni-44Ti/TZM interface zone, forming a metallurgical bond between the braze filler metal and TZM. However, a serious intergranular infiltration phenomenon is observed when Ni-44Ti braze filler alloy is used to braze TZM alloy. The degree of intergranular infiltration and corrosion of the base material significantly decrease with decreasing the Ti content in the braze filler alloy. The average shear strength of TZM/Ni-13.7T/TZM brazed joints reaches 193 MPa, while that of TZM/Ni-44Ti/TZM brazed joints is 167 MPa. The lower shear strength of TZM/Ni-44Ti/TZM is attributed to the intergranular infiltration due to the higher content of Ti in the brazing filler.
