METALLURGY
Academic Year 2022/2023 - Teacher: FABIO GIUDICEExpected 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 in operating conditions, and the effects of the main technological treatments. 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 interpret the degradation phenomena of metal alloys in operating conditions, and to 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.
During the course, on-going tests are foreseen. 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.
Examples of frequently asked questions and / or exercises
