Molecular dynamics study of liquid metal infiltration during brazing

Molecular dynamics (MD) simulations are presented to investigate the rate of infiltration of liquid Cu through a channel in crystalline Ni. Two temperatures, T=1750K and 1500K, are studied using two types of simulations: non-dissolutive (ND), where Ni atoms are held fixed, and dissolutive (D), where Ni atoms relax according to MD equations of motion. At T=1500K the penetration rate agrees well with theoretical models based on capillary forces, …
