The lectures are related to the modern metallurgy as it is applied in all aspects modern and daily life. The interaction of metallic materials with the surrounding environment (i.e. manufacturing, operating, exposed environment) is taken into account. The classes are enriched by case studies and other activies meant to sustain the curiosity and the attention of the students
This Classes are offered to students having acquired the credits of Metallurgy 1 or an equivalent course
To consolidate the knowledge about steels, learn elements about non ferrous alloys Cu and Al based. The following notions are also offered: copper and copper alloys castability evaluation, introduction to welding tecniches, Metals and steels in renewable energies with special attention to fuel cells (PEMFC, SOFC). Corrosion and protection. Metals in cultural heritage.
The student is supposed to gather the following skills: to know how to read a technical sheet about a steel and a metallic material in general; to know the effect of each alloying elements in steels; To know special steels, low and high alloyed steels, special purposes steel, Stainless steels; to know how to read chemical, physical and mechanical data specified in the materials datasheets. To settle an experimental protocol for the characterization of materials and for their qualification is also a skill demanded to the student after the classes. The student should be able to select the best alloy for an application to establish the corrosion risk and the related counter strategy
Lectures are mostly held in the classroom with the participation of experts. One credit of experimental activities is carried out as final experience of the teaching program.
A copy of the power point is given at the conclusion of the teaching period.
Strengthening methods in steels: alloying, cold hardening, ageing, secondary hardening. Detailed description of classified commercial steels: from micro-alloyed to highly alloyed steels (e.g. HSLA, maraging, duplex, weathering, micro-alloyed, Austempering). Stainless steels. Powder metallurgy. Room temperature corrosion, high temperature oxidation and related electrochemical measurements. Materials in renewable energies, fuel cells, stacking
