1. 20 years of materials science: results and perspectives for the future
Jacques LEVY
President of ARIEL

2. The great technological programs: the driving force for materials science and engineering
Development of nuclear energy
Aeronautics and aerospace
Automobile
Electronics and computers
Etc…

3. "Hyper-choice" of Materials: the golden age of Materials
Ferrous and non ferrous metals and alloys
Polymers
Ceramics
Electronic materials
Reinforced composites
« sandwiches »
Biomaterials
Polycristals (grain size)
Single crystals
Fibers
Powders
Nanomaterials
Etc…

4. Hard times for materials!….
Development of computers
Increase of productivity and competition
Constant reorganization of industry: collapse of steel, aluminium, non ferrous metals, chemical industries in western countries
Decrease of funding for research and development
Decrease of interest of students for these topics

5. Evolution of the French steel industry

6. Evolution of world steel industry

7. Evolution of China steel consumption

8. Symmetrical tilt boundary in aluminium (001)-53°

9. Pure aluminium

10. Future prospects
Development of China,India,Brazil boosts energy and materials consumption
Geopolitics lead to increased instability,hence to a growth of defence expenses
More interest in research in the materials field

11. Conclusion
The demand for more research in the field of materials is likely to grow rapidly
The only way to face the increasing cost of investigations in materials science is to build cooperative programs
The France-NCEM (Berkeley) 20 years old cooperation is an interesting model which should be extended and duplicated
