Abstract

The combination of different chemical elements allows to obtain new and improved materials, as required for novel applications. Especially directionally solidified multicomponent eutectic alloys exhibit a wide range of patterns in the microstructure, which are correlated to the mechanical properties. The pattern formation during solidification depends on the chemical elements and the applied process parameters. Large-scale phase-field simulations are used to study the pattern formation of directional solidified ternary eutectics. Three different systems, starting from a model system towards the system Al-Ag-Cu are investigated, using three growth velocities. The three-dimensional simulation results are quantitatively compared and a broad variety of arising patterns for the studied systems is found. The results of the velocity variation follow the predictions from the analytic Jackson-Hunt approach.
