摘要

Reactive multilayer nanolaminates (RMNL) can be useful for precision bonding of microscale components or other novel nanoenergetics applications. This modeling study of RMNL investigates the steady and periodic advancing characteristics of reaction front by employing simplified atomic diffusion and thermal diffusion model. The numerical results shows that the atomic premixing at layer interface greatly reduces reaction front speed, as the premixing degree becomes larger. Also, transition from steady propagation of reaction front to two distinctively different oscillatory propagation types of periodic advancing patterns are found and analyzed. At high level of atomic premixing, reactive bonding may experiences significant non-uniformity in spatial temperature distribution due periodically occurring temperature overshoots, and it may adversely affect bonding or joining integrity.
