摘要：
In this study, Cu-Sn-Ti active brazing alloys were prepared by vacuum induction melting. The microstructure and melting properties of as-cast Cu-Sn-Ti alloys were analyzed using scanning electron microscopy and differential scanning calorimetry. The optimal 87Cu-8Sn-5Ti paste was used for Al2O3/Cu brazing, and the sound joints were obtained in vacuum at 930 degrees C for 10 min. The joint microstructures were studied by means of SEM and EDS. The results show that there exist three zones in the brazing seam and the bonding area of the joint mainly consists of TiO, Cu3Ti3O and Cu-Ti compounds. The maximum value of the tensile strength of brazed joints reached 154 MPa.
