Short- And Intermediate-Range Structure And Dynamics Of Fe-Ni-C Liquid Under Compression, Jianwei Wang
Short- And Intermediate-Range Structure And Dynamics Of Fe-Ni-C Liquid Under Compression, Jianwei Wang
Faculty Publications
Properties of liquid Fe alloys under high-pressure conditions are crucial for understanding the composition, thermal state, and dynamics of Earth's core. Experiments on such liquids, however, are often performed under pressures far below those of the outer core, necessitating long extrapolations of experimental results to core conditions. Such estimates can be complicated by light elements possibly forming pressure-dependent molecular clusters that can significantly affect the physical properties of liquids as core conditions are approached. First-principles molecular dynamics simulations were employed to compute the properties of an Fe-Ni-C liquid with a composition of Fe3.7Ni0.37C at 1673 K and pressures from 0 …
