Comment on “Phase stability and segregation behavior of nickel-based nanoalloys based on theory and simulation”

In a recent paper, Zhao et al. [Journal of Alloys and Compounds (2017), doi: 10.1016/j.jallcom.2017.03.027] studied the Ni-Pt, Ni-Ir and Ni-Ru phase diagrams at the bulk and nano-scales by using an ideal solution model. In this comment, we demonstrate that the correct way to predict those phase diag...

Description
Summary:In a recent paper, Zhao et al. [Journal of Alloys and Compounds (2017), doi: 10.1016/j.jallcom.2017.03.027] studied the Ni-Pt, Ni-Ir and Ni-Ru phase diagrams at the bulk and nano-scales by using an ideal solution model. In this comment, we demonstrate that the correct way to predict those phase diagrams is to use a non-ideal solution model as shown by the comparison between the theory and the experimental data.
