Presentation Transcript

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

  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
