Figure 4
Mass fractions f_s of the solid d-QC (red) and X phase (blue) versus relative temperature T - T_L, where T_L represents the liquidus temperature of either phase. Both curves were calculated using the recent CALPHAD-based assessment of the Al–Co–Ni system from Wang & Cacciamani (2018

). The first derivative dT/df_s of these two curves in the limit of $[f_{\rm s} \rightarrow 0]$ represents the growth restriction factors (GRF) of the d-QC and X phase (see inset). The X phase has a higher GRF by a factor of around 1.5.
