Development and Characterization of Ag-Cu-Ti Alloys for Ceramic Brazing

Mondal, Sudipta and Pathak, L C and Venkateswarlu, K and Das, S K and Ray, Ajoy K (2002) Development and Characterization of Ag-Cu-Ti Alloys for Ceramic Brazing. In: Proceedings of the Indo-Malaysian Joint Workshop (WAM-2002), 12-13 March, 2002, National Metallurgical Laboratory, Jamshedpur.



In the present investigation, silver and copper base alloys with varying compositions of Ag:Cu = 72:28, 60:40, 50:50 and 30:70 (by wt%) are prepared. In each set, 1, 2 and 3w1% of active filler element, i.e. titanium is incorporated by powder metallurgical route. The samples are characterised by XRD, DTA-TGA, SEM and EDX. The XRD results show that titanium and its related phases are not present due to the lower concentration of Ti in these samples. Energy dispersive X-ray analyses reveal that most of the titanium is present in the copper rich phase and very little in the silver rich phase. The rolled brazing alloys are used for./pining the alumina to alumina, that showed excellent joining characteristics.
