ection III: Supplemental Literature Review
Ni-P (Nickel-Phosphorus) H. Okamoto
The Ni-P phase diagram in [2000Oka] was constructed based on thermodynamic modeling by [1999Shi] (0 to 33.3 at.% P) and assessment by [1991Lee] (33.3 to 100 at.% P). All phases were assumed to be line compounds in [1999Shi].
Table 1 Phase (Ni) Ni3P bNi5P2 aNi5P2 bNi12P5 aNi12P5 Ni2P Ni5P4 NiP NiP2 NiP3 P(red)
[2009Sch] investigated the Ni-P phase diagram based on XRD and EMPA. The result is shown in Fig. 1 (0 to 66.7 at.% P). bNi5P2, bNi12P5, and Ni2P have measurable width (enlarged in Fig. 2). The rest of the phase diagram in Fig. 1 has been redrawn from [1991Lee]. Ni-P crystal structure data are given in Table 1.
