Academic Year 2023/2024 - Teacher: CLAUDIO TOSTO

Expected Learning Outcomes

The aim of the course is to introduce fundamental concepts related to the structure of materials, structure-property relationships, and some of the most important technological transformation processes.n the Materials Science and Technology module, metal and ceramic materials will be addressed in detail by focusing on the properties of engineering interest for a mechanical engineer. An introduction to recent Additive, polymeric, and hybrid Manufacturing technologies will be provided in the final part of the module. By the end of the course, the student must be able to classify different engineering materials, their properties in relation to their structure, and typical applications for each material.

Course Structure

The course will be done through lectures, ongoing tests and exercises

Attendance of Lessons

The student is required to attend at least 70% of the lessons of the course, cf. Point 3.1 of the Teaching Regulations of the CL

Learning Assessment

Learning Assessment Procedures

Frontal and intermediate tests.

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) professor of the Department where the Degree Course is included

Examples of frequently asked questions and / or exercises
