1B. Basic Metallurgy of Aluminium (English)

The course provides a compact introduction to the important points in metallurgy and metal physics of Aluminium and its alloys.

It introduces the basic atomic crystal-lattice structure and microstructural features, the thermodynamic basis of alloys, like phase-diagram, solidification and segregation issues. The principal basic structural effects of crystal-lattice defects are introduced, such as foreign atoms & vacancies, dislocations, grain boundaries and precipitations. These defects explain the diffusion in the crystalline lattice structure and the principal strengthening mechanisms in Aluminium alloys. These are

• Alloy- & solid solution hardening
• Plastic deformation & strain hardening
• Softening mechanisms like recovery and recrystallization
• Precipitation & age hardening

The course provides the necessary physical information for a basic understanding of Aluminium and the specific properties of the different Al-alloys, including its designations and tempers. It addresses some aspects of metal processing and fabrication of semis (castings, extrusions, rolled plate & sheet) and of Aluminium products and applications. It gives further information on other internet info and e-learning tools available, like : “AuMatter”, “AluSelect”, and the “EAA Aluminium Automotive Manual AAM”

This provides the necessary basic information and understanding of Aluminium, its alloys and their specific properties, metal processing and various applications.
