The objective of this course is to understand the basic principles of thermodynamics, and to apply the principles in various phenomena relevant to ferrous metallurgy. The laws of thermodynamics will be applied to gas, liquid, solid systems with special emphasis on iron and steel). Basic solution theory, energy requirements, relations between Gibbs energy and phase equilibria and phase stability will be examined.

An elective course. No prerequisite is required.
