Objectives of the course
The module proposes to correlate the nature and microstructure of non metallic materials with their properties with the aim to identify
more suitable materials, from a technological and economical point of view, for the realization of motor vehicle components.
Expected skills
The student should acquire familiarity with the most common classes of materials and their structural and technological features in order
to be able to choose the most suitable materials for the realization of motor vehicle components.
Prerequisites
It is considered necessary the knowledge of the contents of the Chemistry module.

- Experimental workshop on ceramic materials.


V PART


- Materials and environments; outline of material cycles, containment of consumption, care of the environment, the recovery and
recycling of materials at the end of the motor vehicle's life.
Laboratories and/or exercises
The teaching staff will available to the students for clarifications of subjects discussed in the lessons and for informal verification of the
level of learning.


Training on the indexing of the directions and planes in crystal lattice. ' Training on the thermal properties of materials: thermal
conductivity, thermal expansion, resistance to thermal shocks, thermal capacity,. ' Training in the mechanical properties of materials:
elastic, plastic and viscoelastic behaviour; tensile and transverse flexural tests , creep; hardness; resilience ' Calculation training on
the binary phase diagrams. ' Experimental workshop to determine mechanical properties. Numerical training on fuels.


Didactic Material


Didactic material expressly prepared in relation to the lessons, training and workshops, will be made available to the students.

Supplementary texts are available from the library:

W. F. Smith, Scienza e Tecnologia dei Materiali, McGraw-Hill, 1995.

W. D. Callister, Scienza e Ingegneria dei materiali, EdiSES, 2003.


Exam procedure


The exam is a written exam. The student may request an oral test if he achieves the required marks in the written part. The written
exam consists of answering 10 questions in writing, two of which will be mathematical. The maximum time available is 120 minutes.

The oral tests consist of two or three questions for each candidate, to be developed through discussion and the execution of brief
calculations.
