Course description and aims
Why the steels are widely used in our society? How important the steels are to achieve a safe, reliable and sustainable society? How much the steels are produced? How the steels are produced? The key points to answer these questions are within the steels. This course, “Ferrous Materials I”, gives you the basics and principles of the physical metallurgy of iron and steels. The course, “Ferrous Materials II”, which is linked to this course, provides you opportunities to understand how the steels are produced based on the principles. Students will learn unique characteristics of iron and steels to produce a variety of properties that you want to give through studies on the basis of metallurgy such as phase diagram and phase transformation.
Student learning outcomes
Students will be able to:
1) Understand iron-carbon equilibrium phase diagrams, phase transformations in plain carbon steels and normalized microstructures formed through the phase transformations.
2) Understand the effects of alloying elements on the equilibrium phase diagrams, the phase transformations and microstructure evolutions in steels.
3) Understand the excellent heat treatability of steels to control microstructures, the microstructures being the decisive factor for the mechanical properties of steels, and these points making it possible to use the steels in a variety of applications.
Keywords
