The melting curve of iron at the pressures of the Earth's core from ab initio calculations

Quenching of bcc-Fe from high to room temperature at high-pressure conditions: a molecular dynamics simulation

“…It also allows one to explain a number of features of IC [9,10]. The melting temperature of Fe at the pressure of the outer core-inner core boundary (330 GPa), according to the EAM, is consistent with the temperature computed from first principles [18] (later revised to a somewhat lower temperature) within the mutual error bars. The EAM melting temperature is in agreement with the shock-wave data [3] at a pressure of 243 GPa ( figure 1).…”

Theoretical modeling of molar volume and thermal expansion

“…They concluded that this calculation strategy is expected to be applicable to a wide range of liquid metals. Similar work has been done to calculate the melting curve of iron at the Earth's core (Alfè et al, 1999), and chemical potentials of solid and liquid solutions of the Earth's core (Alfè et al, 2002).…”

X-ray diffraction of molybdenum under shock compression to 450 GPa

“…Similar controversies surround the melting curve and phase stabilities of other transition metals 1 including Ta [29][30][31][32] and Fe [33][34][35][36] , so a better understanding of Mo has broader implications for high-pressure science and geophysics. Previous shock wave studies of molybdenum provided only constraints on the equation of state 16 or sound velocities 2,9,37 and could not directly determine the stability of different phases.…”
