The authors have used microstructural, differential thermal, x-ray phase, and electron probe analysis to study alloys in the Ti-TiNi-NbNi-Nb region of the ternary Ti-Nb-Ni system, both as-cast and annealed at 900{degrees}C. They have located a pseudobinary - <{beta}> section, where {beta} is a Nb-rich (Nb, Ti)-based solid solution. The pseudobinary eutectic point parameters are 1170{degrees}C and 38 Ni 26 Nb (at.%). They have found two invariant peritectic four-phase equilibria for crystallization of the alloys in the region of interest: L + TiNi {leftrightarrow} {beta} + Ti{sub 2}Ni (950{degrees}C) and L + {beta} {leftrightarrow} TiNi + NbNi (1140{degrees}C). The authors have not confirmed the existence of a ternary compound Ti{sub 3}(Ni, Nb){sub 2}.
