Modeling of the sequence of phenomena in brazing

The phenomena involved in a brazing process constitute a set of very complex spatially distributed, transient physical and chemical processes, influenced by multiple parameters. This has been difficult to model reliably. This chapter offers a high level review of three broad areas of modeling: (i) the heating/cooling process during brazing, (ii) the thermomechanical behavior of brazed assemblies, and (iii) micro-scale phenomena, taking place in the joint zone and primarily related to transport phenomena. This discussion illustrates the importance of modeling brazing processes and its increasing contribution to the long-lasting success of the art.
