| Outline and Purpose of the Course | Physical and chemical properties of materials depend on not only lattice structure and composition but also microstructure. In this lecture, the microstructure evolution during phase transformation (i.e. solidification) will be explained by using thermodynamics and kinetics (atomic diffusion, thermal energy transport and momentum transport). Students study the fundamentals of microstructure evolution (nucleation, growth mechanism, solute partition, microstructure selection, dendritic growth, eutectic growth and equilibrium / non-equilibrium processes). | |||
| Course Goals |
1. To understand relationship between microstructure evolution and thermodynamics / kinetics. 2. To be able to use thermodynamics and kinetics for understanding microstructure in materials. |
|||
| Schedule and Contents |
1. Introduction (1): fundamentals of thermodynamics and kinetics, which are required for understanding this class 2. Nucleation (1): classical nucleation theory and curvature effect 3. Interface morphology (1): interface morphology (atomic scale), macroscopic interface shape 4.Growing interface (3): local equilibrium at interface, solute partition, stability of interface 5.Dendritic growth (2): mechanism of dendritic growth, selection mechanism 6.Solute partition and segregation (2): solute partition at interface, segregation (non-uniform distribution of solutes) 7.Eutectic growth (1): cooperative growth (eutectic growth) of multiple phases, selection of microstructure 8.Non-equilibrium phase transformation (1): rapid solidification, non-equilibrium and metastable phases 9. Microstructure evolution (2): relationship between microstructure evolution and phase diagram, selection rules in phase transformation 10. Learning achievement evaluation, and feedback (1) |

| Evaluation Methods and Policy |
Evaluation method: Evaluation will be based on one written examination at the end of semester. Evaluation standard: The result of a written examination should be 60 and above out of 100. (60 and above: Passed, 59 and below: Failed) Evaluation may include short reports. |
