Ti-10Zr-10Cu-10Ni powder was used as a brazing filler for vacuum brazing of commercial pure titanium TA1 at 880 ℃ for 30 min and 910 ℃ for 30 min. Following this, interface microstructure and performance analyses were carried out on two sets of distinct brazed joints. The results show 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/TAl. The Zr elements are scattered 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 of brazed joint, the tensile strength of brazed joint at room temperature is around 174 MPa. The room temperature tensile strength rises to around 491 MPa when it is subjected to 910 ℃. The hardness of the material exhibits a progressive rise from the base material to the welding center. At 910 ℃, the greatest recorded hardness (HV) is around 2842 MPa, while at 880 °C, the maximum hardness (HV) reaches 3724 MPa. The mechanical difference between the two joints is mostly caused by the separation of Zr element, which create 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 ℃ exhibits cleavage fracture characteristics, while at 910 ℃ it demonstrates a ductile fracture mode.
