The Ni-Pt phase diagram in [Massalski2] was redrawn from [1991Nas], which was based on experimental data reported before 1981. Phase boundaries of low-temperature ordered phases have not been well defined.

[1986Cad] reported the phase boundaries of the ordered Ni3Pt, NiPt, and NiPt3 phases. (The NiPt3 phase was missing in the diagram of [1991Nas].) However, boundaries of the low-temperature part of these phases were not well defined.

Figure 1 shows the Ni-Pt phase diagram calculated by [2009Lu]. It may be difficult to confirm the phase boundaries of the low-temperature phases experimentally due to the slow process in reaching the equilibrium state.
