A Multicomponent and Multiphase Model of Reactive Wetting

QC 20120104
A diffuse-interface model of reactive wetting with intermetallic formation is presented. The model incorporates ﬂuidﬂow, solute diffusion, and phase change that are based on the total molar Gibbs energy of a ternary system with fourphases. Numerical simulations were performed successfully revealing the complex behavior of the reactive wettingprocess that include nucleation and growth of an intermetallic phase, and initial rapid spreading followed by a slowand progressive spreading. In addition, the nucleation and growth of the intermetallic phase is shown to be directlyinﬂuenced by its kinetic coefﬁcient or the interface energy associated with it.
