Abstract
Since the 1950s it is known that a formation of columnar microstructure occurs in the seam when brazing steels with different carbon content to liquid copper. Brazed joints with such a microstructure are characterised by a base-material-like strength if the crystallites penetrate the seam. With the aid of thermodynamic relations and fundamental transport properties a physical model was developed which describes the columnar microstructure formation as a function of relevant parameters. The model can be applied in principle to any brazing system with metallurgical properties comparable to those of the Fe-C-Cu system. Furthermore the model was expand to high-alloyed steels as well as nickel and titanium alloys.
