Synopsis of the course
The object of this lecture is to understand basic concepts of phase transformation and microstructure in materials, and to consider nucleation phenomena and growth mechanism. Based on fundamental understanding of thermodynamics of materials and phase diagram, this course focus on kinetics of reaction in materials for 3rd-4th grade students majoring material engineering. In addition, This lecture will cover the theory of reaction and solidification which occur in the phase or on the interface of crystals, phase transformation phenomena with or without diffusion.
