Content

Introduction, organisation, personal work

Chapter 1: Chemical bonds
Ionic bonding, Covalent bonding, Metallic bonding. Weak bonding (Van der Waals, dipolar and hydrogen).
Main material classes: ceramics, metals, polymers.

Chapter 2 : Bonds and material properties
Elastic properties(tensile test, Young modulus, Poisson coeff.)
Thermal properties(dilatation coeff., melting T°, conduction)
Electrical properties(ionic and e- conduction)
Exercise: NaCl cohesion, compressibility
Exercise: Conductivity

Chapter 3 : Crystallography
Lattice (cell, Bravais lattices).
Crystallographic planes and directions(atomic density), reticular distances.
Patterns, crystal=lattice+atomic pattern.
Compact assemblies and main structural types. Metal Structures: fcc, ch, cc. Interstitial Sites. Covalent Structures (diamond),ionic structures.
Reciprocal lattice, definition, properties. Reciprocal lattice for various Crystal systems. Inter-reticular distances. Relation between direct and reciprocal cell volumes.
X-ray Diffraction: Bragg law, diffraction conditions (Bragg relation, Ewald sphere).
Exercise: Sm-Co et C (diamond-graphite)
Exercise: Intersticial sites
Exercice: Reciprocal lattice
Exercice: diffraction diagram

Chapitre 4 : Crystal defects
Binary phase diagram as a tool.
Point defects, solid solutions, diffusion.
Linear defects: dislocations, plasticity, hardening.
2D defects: grains, précipitates, equilibrium phases.
Material structures.
Exercise: phase diagrams
Exercise: Si substrate and epitaxy
Exercise: Al alloys and power lines.

Personal work: use of CES software for material selection.
