Course description and aims
This lecture is designed for students who have already studied "Ferrous Materials I". The purpose of this lecture is to understand the heat treatments, microstructural control, and mechanical properties of iron and steels that are widely used in our society. In this lecture, students learn various steels such as structural steels, high strength/hardness steels, stainless steels, cast irons, and heat resistant steels. Visiting the steelworks is planned.
Student learning outcomes
By the end of this lecture, students will be able to:
1) understand fundamental aspects of practical steels in terms of heat treatment, microstructural control, and mechanical properties.
2) understand the relationship between microstructure and mechanical properties, and surface modification method.
3) design and/or select the proper steels for required properties.
Keywords
application and heat treatments of steels, microstructure and mechanical properties, heat treatment and microstructure, surface modification, visiting steelworks
