Liquid- solid interface migration at grain boundary regions during transient liquid phase brazing

A two-dimensional (2-D) finite difference model has been used to analyze the effect of grain boundary regions on the migration of the liquid-solid interface during transient liquid phase (TLP) brazing of Ni with Ni-11 wt pct P filler metal. This work has been carried out to explain the differences observed between actual and calculated completion times for isothermal solid- ification during TLP brazing and the faster isothermal solidification …
