摘要：

As potential substitutes for traditional Ti(Zr)-Cu-Ni -based brazing metals for high strength Ti alloys as well as a study for metallic glass, Zr-Ti-Ni-based alloys have been attracting much attention recently. In this study, the melting temperatures and microstructures of the Zr(Ti)-rich Zr-Ti-Ni alloys with Ni content below 33.3 at.% were systematically studied. A tertiary deep eutectic alloy consisting of three phases was found at the composition of Zr50Ti26Ni24 with a solidus temperature of 798 degrees C and a liquidus temperature of 809 degrees C, which are significantly lower than the Zr2Ni-(Zr,Ti)(2)Ni pseudobinary eutectic melting temperature of 850 degrees C. This ternary eutectic reaction can be presented as L -> alpha-(Zr/Ti) solid solution + Zr2Ni + ternary Laves (Zr,Ti)(2)Ni.
