Subject fundamentals
The module on Materials Science and Technology is aimed at supply the student with an engineering background on materials, emphasizing the relationships among materials structure, microstructure and performances and, as a consequence, the potentialities of engineering design able to exploit traditional and innovative materials through the tailoring of their microstructure. A deep understanding of the property-limited selection and design is therefore the main objective of this course. Near the analysis of the science that lies behind, some specific case studies will be exploited to allow the student to understand how properties can affect materials selection and processing. In this way, science-led and design-led approaches to materials teaching will be synergically combined to offer the information that will be needed to achieve a deep knowledge and to enable successful material selection.
The module on Technology of Metallic Materials aims to firmly establish fundamentals of metals behaviour especially in respect to their load carrying capacity as influenced by composition, microstructure, thermal and mechanical processing. It comprises half of the course.
Attention is devoted to steels and cast irons and their heat-treating procedures aiming to both bulk heat-treating and surface heat and thermoČ-chemical treatments. The quenching and ageing processes of Al and Mg alloys are fully described. A description of applications of selected classes of steels, Al, Mg, and Cu alloys is offered aiming to guide users to material selection in design and to quality appraisal in procurement. Corrosion environment requirements will lead to stainless steels and Cu alloys description.
Expected learning outcomes
The main aim of the Materials Science and Technology module is to supply the student with a robust background on materials, able to couple scientific and technological knowledge in a synergic way, providing general guidelines for translating scientific knowledge into technological tools for engineering design.
The student should then:
- know the chemical and atomic nature of the materials and the strong dependence of the macroscopic features and properties on it;
- know how to exploit this scientific background in controlling the material properties up to the tailoring of material features for a specific application;
- be conscious of the role of material selection in matching design requirements;
- know a basic English vocabulary on Materials Science and Technology;
- knowledge and understanding of the Fe-C stable and metastabile phase diagrams;
- knowledge of bulk and surface heat-treatments as well as ability to foresee their mechanical properties after heat-treatment;
- to know how to compare performances of steels, cast irons, Al, Mg, and Cu alloys;
- basic knowledge of corrosion and corrosion-resistant alloys;
- to know how to analyse metal microstructure and to perform mechanical properties tests.
Prerequisites / Assumed knowledge
The student is required to have a robust, basic knowledge on Chemistry, Physics, Calculus, and Strength of Materials.
Contents
The main contents of a Materials Science and Technology module for Engineers can be summarised as follows: Structure of crystalline and amorphous materials. Crystal defects. Material structure-elastic behaviour relationships. Material structure-plastic behaviour relationships. Relationships between material structure and other properties (thermal, electrical). Modification of the material properties: microstructural constituents (solid solutions, intermediate phases), phase diagrams and transformations (melting/solidification, precipitation hardening), basic knowledge on thermal treatments, microstructural evolution and consequences on properties. General discussion of the principal classes of the engineering materials (metals, ceramics, polymers, glasses). Mentions to the main types and to their properties. These topics require at least 3.5 CFU and should be integrated by each Teacher with specific arguments dealing with the Studies Course.
The module on Technology of Metallic Materials focuses on properties and heat and mechanical treatment of metals, especially important in the mechanical industries and, in particular, in automotive fabrication. Attention will be devoted to solid solution, strain hardening, grain boundaries, and precipitation strengthening mechanisms, as well as to phase diagrams of Fe, Al, Mg, Cu alloys as a basis for the illustration of their massive and surface heat treatments. Properties of selected classes of steels, cast irons and of Al and Mg alloys for foundry and plastic deformation will be completely examined. Basics of metal corrosion will be given to illustrate stainless steels and Cu alloys behaviour and use in technology.

Assessment and grading criteria
Concerning the contents of the module of Materials Science and Technology, they will be verified by a written test with open questions, calculation exercises and, eventually, multiple response questions on all the topics covered during the course.
As regards the contents of the module Metallic Materials Technology oral interviews will be conducted; they may be partly or entirely substituted by a written test with open questions or multiple response questions on all the topics covered during the course.
The final mark will be the arithmetic average of the results of the two modules upper rounded to 1/30.
