Course contents summary
The course proposes the main classes of ferrous metals (steels and cast iron) and light alloys (Aluminum, Magnesium and Titanium alloys) in order to understand the different types of use. Particular emphasis is placed on the influence of the microstructure on the mechanical properties of the components. The first part of the course therefore focuses on topics of physical metallurgical and fundamentals to have a solid basis for dealing with the different classes of ferrous and non-ferrous alloys envisaged in the program.
Fundamental physical metallurgy: solidification of metals and alloys, laws of diffusion with application to thermal treatments, methods of strengthening.Microstructural investigation Techniques of Metals: Optical and electron Microscopy.Classification of steels (UNI EN). General construction steels (low carbon), special steels (medium and high carbon), maraging steels, tool steels, stainless steels, high and low temperature steels, 13% Mn alloy steels, casting steels. Cast iron: classification, white iron, gray iron, graphite shape and distribution, mechanical properties, perlitic cast iron, alloyed cast iron, spheroidal cast iron, adi.Non-ferrous metals. Aluminum and its alloys: designation, casting alloys, wrought alloys. Magnesium and its alloys: designation, cast and wrought alloys. Titanium alloys.

Assessment methods and criteria
Testing is done with a written test and an oral exam. The written test is divided into 3/4 questions that may relate to the theoretical contents and / or the exercises dealt with during the course. The test is exceeded if it reaches at least 18/30. Oral exam is an integral part of the exam and concerns the written exam or other parts of the exam. The final vote can be increased by 5-6 points. ’30 cum laude’ is given if the maximum score is achieved and mastery of the disciplinary vocabulary is demonstrated.
