| 摘 要： | 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)3Ta NiTa Ni2Ta,were also identified.

| Abstract: | The isothermal section of the Ni-Pt-Ta ternary system at 1173 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 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. |
