The phase equilibria of the Ti–Ni–Sn and Ti–Ni–Sb ternary systems have been studied in the whole concentration range by means of X-ray and EPM analyses at 1073 K and 873 K, respectively. Four ternary intermetallic compounds TiNiSn (MgAgAs-type), TiNi2−xSn (MnCu2Al-type), Ti2Ni2Sn (U2Pt2Sn-type), and Ti5NiSn3 (Hf5CuSn3-type) are formed in Ti–Ni–Sn system at 1073 K. The TiNi2Sn stannide is characterized by homogeneity in the range of 50–47 at% of Ni. The Ti–Ni–Sb ternary system at 873 K is characterized by formation of three ternary intermetallic compounds, Ti0.8NiSb (MgAgAs-type), Ti5Ni0.45Sb2.55 (W5Si3-type), and Ti5NiSb3 (Hf5CuSn3-type). The solubility of Ni in Ti0.8NiSb decreases number of vacancies in Ti site up to Ti0.91Ni1.1Sb composition.
