  The most critical limitation to the wide-scale use of classical molecular
dynamics for alloy design is the availability of suitable interatomic
potentials. In this work, we demonstrate a simple procedure to generate a
library of accurate binary potentials using already-existing single-element
potentials that can be easily combined to form multi-component alloy
potentials. For the Al-Ni, Cu-Au, and Cu-Al-Zr systems, we show that this
method produces results comparable in accuracy to alloy potentials where all
parts have been fitted simultaneously, without the additional computational
expense. Furthermore, we demonstrate applicability to both crystalline and
amorphous phases.
