Goals

Present the mechanisms of plastic deformation in crystalline materials (metals, ceramics) as well as polymers, and the associated physically based constitutive laws.
The microstructural evolution of structural materials subjected to thermomechanical treatments will be presented in detail.

Content

Plastic deformation of polymers (8h) :

Plastic deformation and damage mechanisms of amorphous and semi-cristalline polymers
Theory of Ree-Eyring, of Robertson and of Argon
Numerical modelling Thermomechanical treatments

  • Plastic deformation at low temperatures (14h) :

Dislocations : nature, elastic field, interactions
Quantitative description of yield stress
Thermal activation of plastic deformation
Physically based constitutive laws
Relationship with mechanics and ductility

  • Plastic deformation at high temperature (10h) :

Recovery, recrystallization
Dynamic recovery & recrystallization
Diffusion creep
Grain boundary sliding

  • Thermomechanical treatments (8h) :

Equilibrium microstructures
TTT, CCT diagram
Non equilibrium transformations



Prerequisites

This course is in common between the Materials Engineering program and the International Master "Materials for Nuclear Engineering". As such, it will be taught in English if students are registered in this master course. In this case, the written exam will be proposed in the French & English languages, and the students will be offered the choice to write their exam in any of the two languages.

Tests

The exam may be taken in french or in english FR EN

written exam 2 x 2h



final mark = 0.5 (exam1)+ 0.5 (exam2)

Additional Information

This course is given in english only EN
