The isothermal section of the Ni Pt Ta ternary system at 1?173?K 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 Ni 3Ta and Pt 3Ta was identified. Four binary compounds, i.e. Pt 2Ta, Ni 2Ta, NiTa and NiTa 2, and four three phase fields, i.e. Pt 2Ta+(Ta)+NiTa 2, Pt 2Ta+NiTa 2+NiTa, Pt 2Ta+(Ni, PT) 3Ta+NiTa and (Ni, Pt) 3Ta+NiTa+Ni 2Ta, were also identified.
