A way of coupling ternary phase diagram information with multiphase solidification simulations

Multiphase solidification simulations have become a powerful tool of modeling various aspects of metallic solidification like thermo-solutal convection, feeding flow, macrosegregations and others. However, a necessary step towards practical application is the consideration of multi-componental phase diagram information. In the present paper, a general concept is presented which shows how the primary solidification can be modeled by using ternary and higher componental phase diagram information in combination with multiphase process simulation. Based on the presented approach, first results on the formation of macrosegregations during continuous casting of technical bronze alloys are presented.
