computational material science : focused on phase-field model and its applications
computational material science (CMS) has received much attention as a robust tool to study various materials phenomena thanks to great strides in computer performance and materials theories.
In this presentation, various methods of computational materials science are briefly introduced and the phase field model and its applications to various fields are reviewed. The phase field model is known as one of the most accurate computational methods to describe the interface dynamics. As the phase transformation proceeds by the movement of the various interfaces existing in the material microstructures, the characteristics of the phase transformation are governed by the thermodynamics and dynamics of those interfaces. Therefore, the phase field model can be said to describe all kinds of phase transformations most accurately. In this presentation, the brief introduction of the phase field model is given and the developments and applications of the phase field model conducted with our coworkers are reviewed briefly. The topics include peritectic solidification, austeniteferrite transformation and martensitic transformation in steels, particle-splitting in Ni-based superalloy, grain growth and texture evolution driven by elastic interaction, etc.
