Kursplan för studenter höst 2024

After a successful course, the student shall:

• display knowledge of the common impurities and tramp elements in aluminium and their removal
• demonstrate comprehension of the industrial practice for the treatments of aluminium alloy melts

• demonstrate the ability of selecting a suitable treatment process for a specific aluminium alloy and casting process through the use of thermodynamics and kinetics for the intended reactions and process steps

• demonstrate the ability to predict the required additional amounts and treatment times for the intended and judging if the process outcome had the intended effect

The critical content is related to the aluminium alloy preparation including, light metal scrap recycling technologies, melt refining and impurity control to enable sustainable management of circular materials. The practices for microstructural engineering such as grain refinement and microstructural modification.

The course includes the following elements:
1. The effect of dissolved impurities and inclusions on the mechanical properties of metal products ;
2. Thermodynamics and transport properties ;
3. Properties of various metals, impurity content, and refining ;
4. Removal of dissolved impurity elements from molten metals ;
5. Removal of inclusions ;
6. Addition of alloy components ;
7. Solidification and refining ;
8. Refining and recycling metallurgy in the future;
9. Industrial practice for aluminium alloys;

Lectures, assignments and discussion forum.
