Crystallography - 4PMFMOFM

Goal(s)

Course 1 : Crystallography (10h CM- 14hTD)

This course provides an introduction to crystallography. It covers crystal structure and symmetry, with a particular focus on X-ray diffraction. Understanding the structure of a material is often essential to explain its properties. To probe the structure of matter, one can use X-ray, electron, or neutron diffraction.

By the end of the course, students should be able to describe any crystal structure and determine a structure based on the analysis of an X-ray diffraction pattern.

Course: Microstructures and properties (12h CM- 8hTD)
To give information about the links between microstructural parameters (defects, grain size…) and both mechanical properties (hardening, brittleness, plastic deformation) and functional properties (electric, magnetic…) of metals, ceramics and polymers.

Content(s)

Course 1 : Crystallography (10h CM- 14hTD)
Summary
1/ Introduction
2/ Direct and recirocal lattices, lattice classification
3/Study of crystal symmetries, space groups, point groups
4/ X-ray scattering
5/ Experimental methods and case studies

Chapters 2 and 3 deal with geometrical crystallography. The importance of the symmetry of crystals will be emphasized. Examples will be analyzed only from a structural point of view. Questions about the origin of a given structure or chemical bonding are out of the scope of the lectures.
Chapters 4 and 5 on X ray scattering are illustrated by tutorials on relevant examples of crystal structure determination.
