METALLURGY

Academic Year 2023/2024 - Teacher: FABIO GIUDICE

Expected Learning Outcomes

The aim of the course is to provide the knowledge on the basic phenomena of metallurgy, to understand the properties and the behavior of ferrous and non-ferrous alloys, and the effects of the main technological treatments, also in relation to different types of conditions of use, with particular reference to the main degradation phenomena of metal alloys in operating conditions. This knowledge will be completed by introducing the problems related to the environmental impact of production, use, and disposal of metallic materials. Lastly, the course aims to put the student in the conditions to understand the origin of the material properties, select the most appropriate material for the specific application, define the most suitable treatment to improve its properties according to the conditions of use, and make assessments in terms of environmental sustainability of the chosen solutions.

Course Structure

The course includes theoretical lessons, supplemented by exercises and application examples.

Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.

The teaching material consists of the slides of the lessons and additional documentation (studium.unict.it).

Learning Assessment

Learning Assessment Procedures

The learning assessment consists in a final oral exam. Elements to be evaluated: relevance of the answers, quality of their contents, ability to connect with other topics within the program, ability to report examples, quality of technical language, and overall expressive ability.

During the course, intermediate tests will be planned. These tests are optional. Failure to participate does not preclude access to the final oral exam, nor does it affect the final outcome of the same.

Learning assessment may also be carried out on line, should the conditions require it.

To guarantee equal opportunities and in compliance with current laws, students can request a meeting in order to plan any compensatory and/or dispensatory measure, according to the educational goals and specific needs. In this case, it is advisable to contact the CInAP (Centre for Active and Participated Integration - Services for Disabilities and/or SLD) reference professor of the Department where the Degree Course is included.

Examples of frequently asked questions and / or exercises
