Learning outcomes

At the end of the course, the student gains knowledge about: a) effect of chemical composition and microstructure on mechanical properties of light alloys; b) manufacturing processes and heat treatments for obtaining appropriate microstructures with high performances; c) physical, chemical and mechanical properties of light metals.

Moreover the student will be able to define the most appropriate alloys, manufacturing processes and heat treatments for the production of different industrial components.

Teaching methods

Class or on-line lectures according to the timetable

Assessment methods

The final examination consists of a written test (45 minutes) on the EOL web site and an oral examination aiming at assessing if the student learned how (i) to select light alloys and treatments for producing mechanical components that work in a given service condition and how (ii) to identify the reasons for malfunctioning related to material features.
