### Objectifs

The objective is to introduce basic knowledge of Materials Science, required to understand materials behaviour in Nuclear Plants

After completion of this course the student should be able to :

Calculate normal and shear components on a given plane knowing the stress /strain matrix.
Conduct experimentally basics mechanics test and analyse the results
Distinguish the different phase of a microstructure and relate them to phase diagram
Utilize the different diagram to propose for metallurgical heat treatments

Contenu

The course is divided into two main parts:
1) Microstructure of alloys and their specificities
2) Materials mechanical behaviour
During all the lectures, stress will be put on the interaction between microstructures and mechanical properties. And the bases of corrosion and electrochemistry will be introduced.
1) Alloy microstructures and their specificities

Introduction to phase diagrams: definition, binary phase diagrams, introduction to ternary phase diagrams
Defects: vacancies and interstitials, screws and edge dislocations and grain boundaries
Diffusion mechanisms and diffusion equations
Phase transformations: driving forces, liquid and solid phase transformations, TTT-TRC curves
Microstructures: basic of crystallography (texture)
Recovery and recrystallization
Tutorials: Observations and characterisation techniques (TEM, SEM…), applications to selected materials

2) Materials mechanical behaviour

Plastic deformation: dislocations mechanisms, hardening mechanisms (Schmidt law)
Basics of continuum mechanics (stress, strain), introduction to finite element method
Creep of metals and alloys: mechanisms and constitutive equations
Fracture: brittle fracture, fracture toughness, K1c
Mechanical fatigue
