The potential was developed to simulate the plastic deformation in austenitic steels. All pure element have correct melting temperatures. The Ni part is new and different from the Ni potential published in [M.I. Mendelev, M.J. Kramer, S.G. Hao, K.M. Ho and C.Z. Wang, Phil. Mag 92, 4454-4469 (2012), KIM item https://doi.org/10.25950/ebd6cbc4 ]. The Fe part can be used to simulate the fcc phase and the fcc-bcc transition.
