Pre melting in iron and iron alloys: ab initio calculations and high P-T experiments on iron, iron alloys and other materials

The questions this proposal seeks to address are these: are the pre-melting effects suggested to occur in iron at the conditions of the Earth's inner core really there, are they seen across PT space in both iron and iron alloys, and are they seen in other materials? If the answer turns out to be "yes", all models for the dynamics and evolution of the Earth's core will have to be re-evaluated.For over 80 years, the Earth's core has been considered to consist of an iron-nickel alloy, with a few percent of light alloying elements. The pressure range in the core is ~135
