Abstract: The isothermal section of the Ni-Pt-Ta ternary system at 1173K was determined by means of the diffusion triple technology and the electron microprobe analysis. The phase relations in this system were studied. Linear compound (Ni, Pt)₃Ta with small solubility forming between Ni₃Ta and Pt₃Ta was identified. Four binary compounds, i.e. Pt₂Ta, Ni₂Ta, NiTa and NiTa₂, and four three-phase fields, i.e. Pt₂Ta +(Ta)+NiTa₂, Pt₂Ta+NiTa₂+NiTa, Pt₂Ta+(Ni, PT)₃Ta+NiTa and (Ni, Pt)₃ Ta+NiTa+Ni₂Ta, were also identified.
