Sviluppare nello studente le conoscenze di base sulla scienza dei materiali in particolare sulla struttura dei materiali, e sulle correlazioni di questa rispetto alle proprietà chimico,fisiche e meccaniche e fornire informazioni su come sia possibile modificare le strutture con trattamenti fisici e chimici al fine di modificarne le proprietà ingegneristiche. Presentare i concetti di base relativi alle trasformazioni di fase e ai meccanismi di rinforzo. Introdurre lo studente alle prove sui materiali. Fornire allo studente un quadro il più ampio possibile delle proprietà di leghe metalliche, materiali compositi e ceramici, con particolare riguardo al loro utilizzo nel veicolo.

Learning outcomes

Knowledge and understanding: Through lectures, seminars and audio / video materials, students learn the basics of materials science applied to automotive and related technologies of production and gains the ability to solve simple problems regarding mechanical properties, phase diagrams and diffusion. Applying knowledge and understanding: Through exercises in class, the student is able to apply his/her knowledge to the design of a heat treatment, the design of simple structures and to forecast the consequences of a heating / cooling stage Making judgments: Through the presentation of different interpretations for the same phenomenon, the student is led to develop independent judgment; exercises with results "impossible" or infinite solutions enhance the ability to develop critical judgment. Communication skills: direct participation in exercises, in which the students have to communicate the results of their individual work Learning skills: the activities described allow the student to acquire the methodological tools to continue their studies and to be able to independently investigate the topics of interest.
