LEARNING OUTCOMES

This course aims to provide an in-depth knowledge of non-ferrous alloys properties and their applications. It has been designed to extend the basic notions acquired during the Metallurgy I course. In particular, several aspects of physical and mechanical metallurgy will be applied to the most diffused non-ferrous alloys. Additionally, knowledges on mechanical processing, heat treatments, welding and corrosion will allow a critical choice and understanding of their behavior at operating conditions.

AIMS AND LEARNING OUTCOMES

The aim of the course is to extend the student’s knowledge on metallic materials by introducing the mechanical and physical properties of non-ferrous alloys. Together with the basic notions acquired in Metallurgy I, the study of non-ferrous materials will allow a wider understanding of metals properties during processing and operating conditions.

At the end of the course, the student will have acquired a detailed knowledge of the main non-ferrous materials about their production, mechanical processing, thermal and chemical treatments, corrosion behavior, and applications. Practicing with the designation systems introduced in this course will enable the recognition of specific alloys and their supply conditions.

PREREQUISITES

Each topic covered during the course will be widely introduced. However, to better address the contents, students must have acquired the basic notions covered in “Metallurgy I” course such as phase diagrams, heat treatments, metallography, crystallography and mechanical testing.

TEACHING METHODS

The course consists of 6 CFU divided in 5 CFU of traditional lectures (40 hours) and 1 CFU of laboratory activities (13 hours).

Lectures will cover the theory and application examples. The laboratory activities include the application of thermal and mechanical treatments on non-ferrous alloys. Samples will be prepared for microstructural observations in order to evaluate the effects of the applied treatments. Also, corrosion tests will be carried out on several alloys in order to study their properties in different operating conditions.

The 4 CFU version of this course consists in 32 hours of traditional lectures.

SYLLABUS/CONTENT

The course will provide an introduction to the most diffused non-ferrous alloys. The first part of the program is focused on the physical metallurgy of non-ferrous alloys. This part will cover the strengthening mechanisms and microstructural aspects of thermal treatments, mechanical processing and welding. Notions on wet corrosion and high-temperature oxidation will be also provided. 

The second part of the program will cover specific non-ferrous alloys including those based on aluminum, magnesium, titanium, copper and nickel. For each alloy will be introduced the production processes, classification, properties and applications.
