    Abstract:

    The microstructure and melting characteristic of the Ti-25.65Zr-13.3Cu-12.35Ni-3Co-2Mo fillers prepared via casting and rapid solidification technology, as well as the interfacial microstructure of the brazed γ-TiAl joint were analyzed by SEM, EDS, XRD, TEM and DSC. The tensile strength of the brazed joint was also evaluated. The results show that the Ti-25.65Zr-13.3Cu-12.35Ni-3Co-2Mo filler prepared by rapid solidification is fully amorphous. The amorphous filler shows thinner melting temperature interval and better wettability to γ-TiAl compared with the crystalline filler. The joints brazed with crystalline and amorphous fillers are both composed of a central brazed layer II between two interfacial reaction layers I, and the tensile strength first increases and then decreases in the brazing temperature range of 925 - 1050 °C for 10 min. However, the tensile strength of the joints brazed with the amorphous filler is always much higher than that with the crystalline filler, and it obtains a maximum value of 302 MPa at temperature of 1000 °C with a holding time of 10 min.
