Modified embedded-atom method interatomic potentials for Mg–Al–Ca and Mg–Al–Zn ternary systems

open access: yesJournal of Magnesium and Alloys, 2021
Al, Ca, and Zn are representative commercial alloying elements for Mg alloys. To investigate the effects of these elements on the deformation and recrystallization behaviors of Mg alloys, we develop interatomic potentials for the Al–Ca, Al–Zn, Mg–Al–Ca ...

The Modified Embedded Atom Method [PDF]

open access: yesComputational Material Modeling, 1994
Recent modifications have been made to generalize the Embedded Atom Method (EAM) to describe bonding in diverse materials. By including angular dependence of the electron density in an empirical way, the Modified Embedded Atom Method (MEAM) has been able to reproduce the basic energetic and structural properties of 45 elements. This method is ideal for
