  • Patent number: 8486330
    Abstract: Disclosed is Zr—Ti—Ni(Cu)-based filler alloy composition having low melting point for brazing titanium and titanium alloys. The Zr—Ti—Ni(Cu)-based alloy composition is expressed as: ZraTibNic (Formula 1) where a, b and c denote atomic % of Zr, Ti and Ni, respectively; 47?a?52; 24?b?30; 22?c?26; and 0.3<c/(a+c)<0.35, or ZraTibNicCud (Formula 2) where a, b, c and d denote atomic % of Zr, Ti, Ni and Cu respectively; 48?a?60; 20?b?28; 19?c+d?30; 3?d?12; and 0.12<d/(c+d)?0.5. Including Zr(Ti) solid solution phase as its major constituent phase, the alloy compositions of this invention have lower liquidus temperature than those of conventional alloys and they include a little amount of Cu or does not include it at all. When alloy of the present invention is used as filler alloy for brazing titanium and titanium alloys, brazing can be performed at remarkably low temperature.
