Abstract

In the present investigation, we present our results on characterization of Ti joints, brazed with metallic glass ribbons of Ti₂₀Zr₂₀Cu₄₀Ni₂₀ alloy. Initially, metallic glass ribbons were produced using a vacuum melt spinner and used as filler materials for vacuum brazing of two Ti alloy plates at 1270 K. Field-Emission Scanning Electron Microscopy (FESEM), the as-spun ribbons showed fully amorphous structure when examined on both surfaces by XRD and also verified by TEM investigation. The detailed DSC results revealed that the amorphous phase crystallized at approximately 753K. The brazing joint of two Ti-plates using the metallic glass ribbon was found to be very sound. FESEM characterization of the cross-sectioned brazing joint shows sub-micron size grains uniformly distributed in the matrix with brighter appearance. EDX analysis revealed that the sub-micron grains are rich in Ti, while the matrix phase has Zr-enrichment. Back Scattered Electron (BSE) image also suggested substantial reaction of the brazing ribbon with Ti plates, whose typical lath microstructure is modified to nanostructured lamellar eutectic microstructure comprising of Ti-rich and Zr-enriched phases.
