96189 - METALLURGIA M

Learning outcomes

At the end of the course, the student gains knowledge about: a) the mechanical, physical and chemical properties of the alloys mainly used in the industrial manufacturing; b) the criteria for the choice of the most appropriate alloys for the production of components, also taking into account the manufacturing processes, the heat treatments, the costs and the entire value chain.

Course contents

Introduction
Basics on metal alloys: phase diagrams, microstructure, solidification, plastic deformation, strengthening mechanisms.
Ferrous Alloys
Extraction processes and recycling. Fe-C phase diagram.
Designation, microstructure, heat treatments surface modification treatments, mechanical, chemical, physical properties and applications of: steels, cast irons and stainless steels.
Non Ferrous Alloys
Alluminum, Magnesium, Titanium and Copper alloys: extraction processes and recycling. Designation, microstructure, heat treatment and surface modification, mechanical, physical, chemical properties and application.
Criteria for the selection of metal alloys.
The most important database with the chemical, physical and mechanical properties of the alloys available on the market and of the possible suppliers will be illustrated. The criteria to define the most appropriate alloys, heat treatment or surface treatment will be discussed considering both technical and the economic aspects.

Teaching methods

Class lectures according to the timetable and workshops with experts from industrial sector. 

Assessment methods

The final examination consists of a written test (45 minutes on the EOL website) and a oral examination, aiming at assessing if the student learned how (i) to select metallic materials and treatments for producing mechanical components that work in a given service condition and how (ii) evaluate the economic aspects of the choice of the use of different metallic materials of different heat treatments for the production of parts.
