Abstract

<p>In this chapter a review is given of work carried out to couple efficiently the macroscopic process scale and the microscopic material scale for solidification processes. Different models were developed or extended to predict the microstructure evolution or significant microstructure parameters. These models were coupled more or less intensely to macroscopic software tools depending on the calculation efforts of each microscopic model. The software packages were validated by designed casting experiments on a laboratory scale. Casting was the first process step within different process lines using different material groups. Numerical techniques and data were exchanged among the partners to carry out the calculations and to develop the models, which comprise the phase field method, the cellular automata method, a microsegregation model, and a semiempirical approach.</p>
