C-MAC Euroschool 2011

22 May - 27 May 2011, Toulouse, France

Structure and crystal chemistry of complex metallic alloys

Organizing committee:

C. Tendero (CNRS, Toulouse), C. Vahlas (CNRS, Toulouse), G. Kreiner (Max Planck Institute, Dresden), M. de Boissieu (CNRS, Grenoble), Roxane Castanet (CNRS, Toulouse)

Presentation of the school:

Complex metallic alloys (CMA) are metallic alloys whose unit cell is very large or even infinite as in the case of quasicrystals.  The detailed understanding of their structure, including long range order, local order and disorder, and the structure/physical properties relationship remains one of the main challenges in this field.

The purpose of the school is to give the basis of the crystallography and crystallo-chemistry allowing a better understanding of those materials.  A thorough introduction to the concepts of crystal chemistry and chemical bonding will be given and followed by its application to CMA. The problem of disorder which is almost always present in CMA and its analysis by diffuse scattering will then be presented. The last part of the school will be dedicated to an introduction to transmission electron microscopy and to metallurgical problems encountered in the aeronautic industry. A visit of the Airbus Company plant will conclude the school. Lectures will be organized on a step by step basis and tutorials organized so as to apply the notion learned.

Participant will have the opportunity to present their work during a poster session.
