授業の目標 Objectives:
The development of alloys is usually aimed at improving oxidation resistance, as well as improving mechanical properties. In this
course, to acquire basic knowledge of thermodynamics and kinetics in the reactions of metals and alloys with gaseous environments
at high temperatures is aimed. In particular, oxidation mechanism of metals and alloys is discussed on the basis of fundamental
parameters of oxides such as point defect structures and transport properties of oxide scales. The final goal of this course is to acquire
basic skills which can be utilized to analyze oxidation mechanism of metals and alloys and design new oxidation-resistant materials.
