Plots of deuterium/hydrogen concentration (x) versus T for hcp and fcc Fe phases. Pressure values in GPa are shown on each plot. Symbols and colors are the same as those in Fig. 1. Data from previous studies (blue circles from Ikuta et al.16 and red diamonds from Iizuka-Oku et al.17) are also plotted. Dotted yellow lines show P–x–T relations in the Fe–H system of Hiroi et al.34. The miscibility gap they reported is shown at x ~ 0.4 as a dotted horizontal line.
