A Computational Study Of The Phase Diagram Of Metals

Using molecular simulation, we compute the full phase diagram of metals, modelled by a many-body potential. The many-body potential considered in this study is the so-called embedded atoms model, introduced by Daw and Baskes. The phase diagram so obtained is then used to understand and interpret the crystallization process from a supercooled liquid metal.
