Ti-10Zr-10Cu-10Ni powder was used as a brazing filler for vacuum brazing of commercial pure titanium TA1 at 880°C for 30 minutes and 910°C for 30 minutes. Following this, interface microstructure and performance analyses were carried out on two sets of distinct brazed joints. The results showed that the microstructure of the two sets of joints is made up of TA1+acicular α-Ti+eutectoid (α-Ti + (Ti, Zr)2(Cu, Ni) + residual filler. The Zr elements are scattered both in the eutectoid structure, residual filler and acicular α-Ti, while the Cu and Ni elements are mostly distributed in the eutectoid structure and residual filler. The mechanical properties of the two types of brazed joints differ significantly. When exposed to a temperature of 880°C, the brazed joint"s tensile strength at room temperature is around 174MPa. The brazed joint"s room-temperature tensile strength rises to around 491MPa when it is subjected to a temperature of 910°C. The hardness of the material exhibits a progressive rise from the base material to the welding center. At a temperature of 910°C, the greatest recorded hardness is around 290HV, while at 880°C, the maximum hardness reaches 380HV. The mechanical difference between the two joints is mostly caused by the separation of Zr elements, which created a brittle, layered intermetallic compound. Fracture analysis of the specimens reveals that the cracks in both sets of interfaces propagate along the weld seams. The fracture surface at 880°C exhibits cleavage fracture characteristics, while at 910°C it demonstrates a ductile fracture mode.
