Literature Data

The Ni-Ta system was studied by several techniques at different temperatures and compositions, which are listed in Table 1. The Ni-Ta binary has been assessed by [1984Nas], [1991Kau], [1994Ans], [1999Cui], [2001Gup], and [2002Pan]. They combined the thermodynamic calculations and published experimental results and re-established the phase diagram. Brief review of phase equilibria were presented by [1996Oka], [2000Oka]. Hence the phase diagram given by [1999Cui] has been accepted. The system exhibits five phases, viz. Ta₂Ni, TaNi, TaNi₂, TaNi₃, and TaNi₈ along with solid solutions (Ni) and (Ta). The composition ranges of phase boundaries and compositions of these phases have been experimentally found out by [1977Pim], [1984Nas] and [1999Cui...
