The present study investigation, our results on characterization of commercially pure-Ti alloy brazed with metallic glass ribbons of Ti20Zr20Cu60-xNix (x = 30, 40, and 50) metallic glass ribbons were produced using a vacuum melt spinner. These ribbons were then used as filler materials for vacuum brazing of two Ti alloy plates at 1268, 1277 and 1279 K for a period of 10 min. Field-Emission Scanning Electron Microscopy (FESEM), Transmission Electron Microscopy (TEM) and the energy dispersive X-ray spectroscopy (EDX). The as-spun ribbons showed fully amorphous structure when examined on both surfaces by XRD and also verified by TEM investigation. The brazing joint of two Ti-plates using the metallic glass ribbon when brazed with Ni50 was found to be of very high strength. FESEM characterization of the cross-section of the brazed joints shows sub-micron size grains uniformly distributed in the matrix with brighter appearance. FESEM and EDX analysis revealed that the sub-micron grains are rich in Ti & Ni while the matrix phase mainly consisted of Ti. BSE image along with EDS Analysis indicated that the brazed joint has a presence of NiTi2 and Cu2 (Ni Zr) phases which could be responsible for increase in the strength of the brazed joint.

This work presents a study of the corrosion resistance as a function of the holding time on the interface generated during the process of brazing an AISI 304 to AISI 316L stainless steels by using a non-commercial Fe60Ni12Cr8P13B7 metallic glass alloy ribbon by induction heating at 1000 °C into a chamber with an Ar controlled atmosphere. Samples of the austenitic stainless steels were joined in a sandwich-like arrangement using the Fe-based metallic glass ribbon. Corrosion experiments carried out in distilled water and 3.5 wt. % sodium chloride solution revealed that the corrosion resistance was higher for samples tested in the distilled water than the latest medium for all dwell joining times, since in the former medium the samples passivated. It was also found that the highest corrosion resistance was achieved for samples joined for a dwelling time of 4 minutes.
