Application of the Phase-Field Crystal Model for Quantitative Materials Modeling

ORAL

Abstract

The recently proposed Phase-Field Crystal (PFC) model [1] can be used to model materials on microscopic length but diffusive time scales. The model can be related to the classical density functional theory of liquids [2] allowing modeling of solidification, phase segregation, grain growth, elastic and plastic deformations in anisotropic systems with multiple crystal orientations. In this talk, I will discuss recent progress on using the PFC model and its extensions to describe quantitative modeling of selected properties of BCC Fe [3]. \\[4pt] [1] K.R. Elder, M.
