Based on an embedded-atom method, an n-body potential is developed for the
Ni-Nb system and the potential is then applied in molecular-dynamics
simulation to study the detailed process of interfacial reaction in an Ni-Nb
sandwich model. It turns out that the solid-state amorphization is initiated
by interface-crossing atomic migration and governed by diffusion-limited
reaction in the Ni-Nb system characterized by a negative heat of formation.
The simulation results are confirmed by thermal annealing experiments
conducted at medium temperatures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
