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
*Be able to investigate creep design in nuclear plant using Ashby maps
The course is divided into two main parts:
*Microstructure of alloys and their specificities
*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.
*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
*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
None
