| Abstract: | TC4 titanium alloy was vacuum brazed with Ti-Zr-Cu-Ni amorphous brazing alloy, and the effects of different holding times on brazed joints were investigated. The optical microscope (OM), scanning electron microscope (SEM), energy data spectrometer (EDS) and micro-hardness tester were used to analyze the microstructure and mechanical properties of the joints. The results show that the main microstructure of the weld was α-Ti and β-Ti, and with the increase of holding time, the weld zone is gradually thickened and the microstructure is gradually coarse. When the holding time was 40 min, the micro-hardness of the weld was the largest, the average hardness (HV) was 328, and the maximum hardness was 335. |
