OVERVIEW

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 one

AIMS AND CONTENT

LEARNING OUTCOMES

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. 

AIMS AND LEARNING OUTCOMES

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

PREREQUISITES

Metallurgy 1

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 copy of the power point is given at the conclusion of the teaching period.

SYLLABUS/CONTENT

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. Materials in renewable energies, fuel cells, stacking

EXAM DESCRIPTION

Oral exam

ASSESSMENT METHODS

The exams is based on the discussions rising from a technical sheet about one of the steel kinds presented during the classes. The metallurgical properties, the effect of alloying elements and the practical applications are the three main topics threated  during the exam. 

3 questions of 10 points each
