Brazing is a relatively high temperature joining process important to a range of metallurgical technology. Brazing depends upon good wettability between constituent materials; furthermore, reactions between solid and liquid are often observed. Understanding fundamental phenomena in high temperature reactive wetting bears potential for impact on technology but also on theoretical descriptions of capillarity. Molecular dynamics (MD) simulations are a useful counterpart to experiment in describing fundamental wetting mechanisms. This talk will review MD simulations of high temperature wetting for metals in a braze geometry. Infiltration of molten metal into a solid pore is simulated for a system where the solid simultaneously dissolves into the liquid. Simulations reveal a regime where the dissolution reaction is aggressive enough to alter the kinetics of infiltration. MD simulations are coupled with Monte Carlo calculations to draw quantitative connections between the free energy of the dissolution reaction and the kinetics of pore infiltration.
