Abstract

 The aim of this study is to start a work about the bonding mechanism of tantalum -to- tantalum brazed by active filler metal alloy which basely stand on using copper or silver with active element such as titanium. Brazing will happen under inert gas (argon). Ag4Wt% Ti,Cu8wt %Ti , and the eutectic Ag 26wt% Cu 4 wt % Ti are the active filler metal which are used , and the bonding phases at the filler metal / tantalum interface line almost contain ( Ti  Ta2 O7 ) and ( Ti0.51 Ta0.49  O2 ) . Which means that active element ( titanium ) shares oxygen with tantalum to make this bond as a cheap filler .
