Solidification as a first-order phase transition is described in the Landau theory by the same equation as tricritical phenomena. Here, the solidification or melting temperature against pressure curve is modelled to end at a tricritical point. The model gives the phase transition temperature’s dependence on pressure up to the quadratic term with a definite expression for the coefficients. This formula is expected to be generally valid for pure materials having melting curves with dT/dP…

Phase Transitions, Melting and Reactions of Stoichiometric Phases

In this chapter we deal with phase transitions, melting and reactions of stoichiometric phases, preceded by a preliminary exposition of the Gibbs Phase Rule. The section on phase transition includes

Molecular dynamics simulation of shock compression of metals: Iron and iron-sulfur solutions

The embedded atom model potential suggested earlier was improved to correctly describe iron at high pressures and temperatures. Correction was introduced using the shock compression data. The

Thermodynamics and Equations of State of Iron to 350 GPa and 6000 K

The equations of state for solid (with bcc, fcc, and hcp structures) and liquid phases of Fe were defined via simultaneous optimization of the heat capacity, bulk moduli, thermal expansion, and

Light matter in the core of the Earth: its identity, quantity and temperature using tricritical phenomena

Light elements in the iron-rich core of the Earth are important indicators for the evolution of our planet. Their amount and distribution, and the temperature in the core, are essential for

PVT equation of state of epsilon iron and its densities at inner core conditions

Abstract The first comprehensive PVT description of ε-Fe is presented by collecting the complete data set of previous experiments on ε iron, covering a pressure and temperature range of 6-306 GPa and



Phase transitions, Grüneisen parameter, and elasticity for shocked iron between 77 GPa and 400 GPa

Sound velocities determined in iron, shock compressed to pressures between 77 GPa and 400 GPa, indicate that two phase transitions exist on the Hugoniot. A discontinuity in sound velocities at 200 ±

The Melting Curve of Iron to 250 Gigapascals: A Constraint on the Temperature at Earth's Center

The melting curve of iron, the primary constituent of Earth's core, has been measured to pressures of 250 gigapascals with a combination of static and dynamic techniques and results imply that the temperature of the lower mantle is significantly less than that of the outer core.

Quasi-Ab initio molecular dynamic study of Fe melting

An ab initio simulated iron melting curve is presented which is in agreement with the low temperatures at lower pressures, but is in excellent agreements with the high-mostly shockwave-temperatures at high pressures.

Melting and crystal structure of iron at high pressures and temperatures

High‐pressure melting, phase transitions and structures of iron have been studied to 84 GPa and 3500 K with an improved laser heated diamond anvil cell technique and in situ high P‐T x‐ray

Iron under Earth’s core conditions: Liquid-state thermodynamics and high-pressure melting curve from ab initio calculations

Ab initio techniques based on density functional theory in the projector-augmented-wave implementation are used to calculate the free energy and a range of other thermodynamic properties of liquid

Stability of the body-centred-cubic phase of iron in the Earth's inner core

The results of molecular dynamics simulations of iron based on embedded atom models fitted to the results of two implementations of density functional theory found that both point to the stability of the body-centred-cubic iron phase at high temperature and pressure.

Melting of iron at the physical conditions of the Earth's core

New and re-analysed sound velocity measurements of shock-compressed iron at Earth-core conditions show that melting starts at 225±3 GPa and is complete at 260 ± 3‬GPa, both on the Hugoniot curve—the locus ofshock-compression states.

Temperatures in the Earth's core from melting-point measurements of iron at high static pressures

THE temperature distribution in the Earth's core places important constraints on the Earth's internal heat budget and on models of the geodynamo. The solid inner core crystallizes from a liquid outer

Temperatures in Earth's Core Based on Melting and Phase Transformation Experiments on Iron

Experiments on melting and phase transformations on iron in a laser-heated, diamond-anvil cell to a pressure of 150 gigapascals show that iron melts at the central core pressure of 363.85 gigapasals at 6350 � 350 kelvin.

Melting of copper and nickel at high pressure: the role of d electrons.

The present results confirm the key role d-shell electrons play in determining the temperature dependence of high pressure melting curves in transition metals that have filled or partially filled d electron bands.
