The Objective of the course is to introduce the student to the fundamental principles of Physical
Metallurgy, which underline the evolution and control of the structure of metals and the way by which structure controls properties. The student should understand the crystal structure of metals as well as the thermodynamics and kinetics of structure as a framework for studying phase transformations. He must become able to perform basic calculations concerning phase diagrams, diffusion in metals and alloys as well as to prescribe the basic heat treatments of metallic materials.

Crystal structure of metals – Grains and grain boundaries – Phases and interphase boundaries – Thermodynamics of structure – Gibbs free energy of Alloys and thermodynamic equilibrium – The Gibbs phase rule – Binary phase diagrams – Kinetic processes in materials – Diffusion and Fick’s law – Phase transformations – Nucleation and growth of a new phase – Annealing and recrystallization of metals – The Fe‐C system and steels – Martesnitic transformations and hardenability of steels – Heat treatment of steels – Light alloys – Precipitation strengthening and aging – Aluminum, magnesium and titanium alloys – Superalloys.
