An n-body potential is constructed for the Ni-Mo system based on the
Finnis-Sinclair formalism. The potential with optimized parameters is able
to reproduce some physical properties of several Ni-Mo equilibrium and
metastable alloy phases. Molecular-dynamics simulation with the constructed
potential is performed to study the detailed process of interfacial
reaction in a Ni/Mo bilayer upon annealing at medium temperatures of 300 to
and reveals that amorphization is driven by mutual atomic
diffusion and follows exactly a 
law.
