Physics of materials

PHYS-307 / 4 crédits

Enseignant: La Grange Thomas

Langue: Anglais

Summary

This course illustrates some selected chapters of materials physics needed to understand the mechanical and structural properties of solids. This course deals primarily with the physics of dislocation. The course also links diffusion kinetics to the fundamental physics of phase transformations.

Content

1. Materials, definitions, structure

Binding energy in metals, ceramics and polymers. Crystal structure and amorphous materials. Theory of elasticity: stress and strain fields.

2. Diffusion

Diffusion in alloys. Physical and chemical diffusion.

3. Plastic deformation and dislocations

Phenomenology. Deformation of single crystals. Burgers' vector. Elasticity theory: interactions among dislocations. Creation and annihilation of dislocations.

4. Dislocation dynamics

Friction forces due to the lattice, to point defects and to dislocations. Movement equations. Partial dislocations and stacking faults. Dissociation mechanisms: dislocations in face centred cubic metals.

5. Dislocation kinetics

Thermal activation of plastic deformation. Dislocation climb. Deformation tests. Relaxation phenomena and mechanical spectroscopy.

6. Thermodynamics of phase transformations

Thermodynamical principles of phase transformations.Phase diagrams. Alloy solidification. Solid-solid phase transformations.

Keywords

dislocations, deformation, diffusion, elasticity, phase transformations, melting, precipitation crystallography

Learning Prerequisites

Learning Outcomes

By the end of the course, the student must be able to:

  • Develop the formalism of dislocation theory
  • Model the plastic deformation of materials
  • Sketch a phase diagram and its thermodynamic basis

Transversal skills

  • Use a work methodology appropriate to the task.
  • Assess one's own level of skill acquisition, and plan their on-going learning goals.

Teaching methods

Oral Lectures and exercises in the classroom. Lecture, exercise and reference materials will be made available on a Moodle. A questions and answer forum is also available on the moodle. Additionally, zoom meeting or in-classroom session will be arranged for exam preperation

Assessment methods

Oral exam in English
