| Learning Outcomes of the Course Unit |
|---|
Student is able to:
- Explain the principal concepts of thermodynamics and their importance in materials study;
- Outline basic processes – solidification and solid phase transformations – in one-component systems;
- Differentiate the behaviour of two-component systems and describe eutectic, eutectoid, peritectic and peritectoid reactions;
- Analyse more complicated binary systems and binary systems with intermediate phases;
- Outline the behaviour of both metastable and stable iron – carbon system and deduce properties of typical alloys.
