In this paper, Ti-Zr28-Cu15-Ni15(1#) and Ti-Zr21-Cu20-Ni15(2#) amorphous filler metals were prepared by rapidly-cooled equipment in order to join the TA15 titanium alloy honeycomb sandwich panel structures. The joint microstructure and tensile strength was investigated by means of SEM, EDS and XRD etc. The results indicated that both of the fillers perform good forming property. Compared with the conventional fillers, the quenching fillers have lower melting temperature and narrow melting temperature range. Filler metal 2# performs higher wettability and glass forming ability than filler metal 1# due to its high percent of eutectic composition. The tensile strength of the brazed joint reached 325 MPa at 970°C for 30 min with filler metal 1#, while the tensile strength of the brazed joint reached 359MPa at 950°C for 30 min with filler metal 2#, and the mechanical stability of the joints is excellent. α+β lamellar structure formed in both joints brazed in the same condition, and smaller amount of Ti-Cu and Ti-Ni intermetallic compounds in the joints brazed with filler metal 2#.
