Force Field

I have looked through the literature quite a bit for a force field for Fe-Cr-Nitrogen

Does anyone know if one exists? I realize this is not specifically a LAMMPS question, but I am curious if anyone who checks this list knows of any type of FF that models this type of a system.



It appears there is none. Depending on what the purpose is, two choices would be to modify an existing ReaxFF description for Fe/Cr/O/S or use EAM description for Fe/Cr alloy and hybrid it with N via LJ.


Here is a MEAM potential for such a system:
