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 one AIMS AND CONTENT LEARNING OUTCOMES The student learns: how to read chemical, physical and mechanical data specified in the materials datasheets; how 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. The studen will have notions on corrosion and special applciations. AIMS AND LEARNING OUTCOMES The student: - learns about steel and special steels - learns the role of alloying elements in iron base alloys and their combined function - becomes aware of special metallurgy and methodologies - becomes aware of additive manufacturing - knows how to read a technical sheet about a steel and a metallic material in general PREREQUISITES The student shall have followed Metallurgy 1 or equivalent teaching lessons. TEACHING METHODS 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 visit to a metallurgical company is planned in the final part of the classes. SYLLABUS/CONTENT Recap on the basic knowledge on metallurgy. Strengthening methods in steels: alloying, cold hardening, ageing, secondary hardening. Effect of alloying elements on steel properties and characteristics. 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. Addittive manufacturing (3D printing). Introduction to room temperature corrosion, high temperature oxidation and related electrochemical measurements.
