Different from conventional modeling tech-niques, the kinetic theory-based background provides the LB models several distinctive advantages in modeling innovation, simulation fidelity, and computational efficiency. Intrinsic features of the LB models allow themselves to model microstructure evolution with other techniques defining growth kinetics of dendrites. A large amount of coupled models have been therefore developed in the past several decades, all of the studies have revealed that the LB method is indeed very promising as an efficient computational tool for the modeling of transport phenomena coupled with phase transformation during solidification. The LB method is an ideal approach for mesoscale and scale-bridging simulations. It is capable to tackling particularly dendritic growth and microstructure evolution with ubiquitous characteristics. Simulations using the LB methods offer insights into the underlying physics of micro-structure formation during alloy solidification.KEYWORDS: solidification, microstructure, dendritic growth, lattice Boltzmann method, alloys
