Phase-field modeling of microstructural pattern formation during directional solidification of peritectic alloys without morphological instability.
TL;DR: A phase-field model of peritectic solidification that incorporates nucleation processes in order to explore the formation of structures and shed light on the morphology transition from islands to bands, the dynamics of spreading of the per architectic phase on the parent phase following nucleation, and the types of growth morphology that one might expect to observe in large samples under purely diffusive growth conditions.
