Interatomic potential for Copper beryllium

HI,

There is no literature available which can suggest the inter-atomic potential for CuBe.
Kindly suggest for this material where metallic bonded system(Cu) is interacting with Covalent bonded system(Be).

Actually Be particles(2%) are diffused in Copper.

There is an EAM description for Be: http://www.ctcms.nist.gov/potentials/Be.html. So in principle you can combine the EAM potentials for Cu and Be together provided that you define (or train, fit, optimize) the Cu-Be cross interactions.
