Mechanical properties of metallic materials are determined by their microstructures. How are the microstructures formed? This course introduces microstructural controlling methods currently used in metallic structural materials, mainly steels, in terms of phase equilibria, kinetics of phase transformations, crystallography and strengthening mechanisms. Students will also learn the principles and philosophy of microstructural design to obtain advanced structural materials.
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.
