摘要: Phase boundaries play an important role in setting the properties of multicomponent materials at both meso- and nano-scales. In this review, we provide overview modelling methods utilized state-of-the-art research engineering applications. We review current physical understanding how phase evolve, focusing on systems. The recent advances numerical modelling, fueled by powerful computers, have provided accurate robust results that allow problems are beyond reach analytic to be addressed. While approaches used engineering-oriented applications employ simplified microstructures, it is found such models quite useful many problems. ability simulate realistic microstructures will further increase power modelling. also highlight differences between sharp interface diffuse for microstructural evolution. addition, identify future topics area.
