Simulation of dendritic-eutectic growth with the phase-field method

Solidification is an important process in many alloy processing routes. The solidified microstructure of alloys usually made up dendrites, eutectics or a combination both. evolving morphologies are largely determined by the solidification and thus materials properties dependent on conditions. While growth either type well-investigated, there little information coupled both microstructures. This work aims to close this gap formulating phase-field model capable reproducing dendritic, eutectic as well dendritic–eutectic growth. Following this, two-dimensional simulations conducted which show all three types microstructures depending composition effect microstructural lengths, determine properties, investigated morphological hysteresis between studied employing velocity jumps. Finally, qualitative three-dimensional test for changes eutectic.
