Abstract

Dendritic competition in solidifying metal alloys is a key component in the formation of the microstructure of metal parts that dictates their material properties. Many 2D studies of dendritic competition have been performed, but these represent a largely idealised representation of the behaviour observed in experiments, overlooking the complexities of the full range of 3D orientations and the impact these geometric changes have on the interaction of grains at a dendritic level. To explore this effect in more detail a parametric numerical modelling study using a Cellular Automata dendritic solidification code has been performed to examine the competition of bi-crystal systems at an industrially relevant scale. For this solidifying system, this study will vary the 3D orientations of the competing bi-crystals, test different thermal conditions, and assess the impact of fluid flow. Where possible reference to observed experimental results will be presented to support the results obtained using the modelling.
