Mechanical properties of steels are determined by their microstructures. This course introduces how the microstructures are formed in steels in terms of phase equilibria, kinetics of phase transformations and crystallography. Students will also learn the principles and philosophy of microstructural design to obtain advanced steels.
Students will:
1) Understand the principle of microstructural design for a variety of applications of steels.
2) Understand the basis of metallurgy (phase equilibria, kinetics of phase transformations and crystallography), which are necessary to design the microstructures.
3) Acquire the metallurgical principles well enough to be able to create new microstructural design methods by themselves.
Thermodynamics of Phase equilibria, kinetics of phase transformations, crystallography, microstructural design principle
✔ Specialist skills | ✔ Intercultural skills | Communication skills | ✔ Critical thinking skills | Practical and/or problem-solving skills |
Exercise problems will be given to promote students' understanding in each class.
