Subject fundamentals
Materials play a crucial role in engineering design and the module on Materials Science and Technology is aimed to 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.
Expected learning outcomes
The main aim 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 from 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.
Prerequisites / Assumed knowledge
The student is required to have a robust, basic knowledge on Chemistry, Physics and Mathematics.
Contents
The main contents of a Materials Science and Technology course 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.
Delivery modes
Some hours will be used for the numerical solution of practical cases

Texts, readings, handouts and other learning resources

Assessment and grading criteria
The exam aims to assess basic knowledge on the various classes of materials and their properties (in particular the mechanical and thermal properties), also by the solution of numeric exercises.
The STM the exam consists in a written test based on six questions and/or exercises similar to those done during STM lectures and covering all the STM program; it will last two hours, the end time will be written on the blackboard; 18/30 is the minimum to pass the exam. 30/30 cum laude (L) is the maximum. Cum laude (L) is awarded to exceptionally good exams, exceeding the maximum, as a discretional decision of the commission. Use of internet, books and notes is not allowed, as well as any communication with other students, which will result with the end of the exam. It is possible to leave the room during the exam, but this means the exam cannot be continued. Exceptions due to proven health issues are allowed. Students are allowed to use their calculator. An identity card with picture must be kept on the desk during the exam, together with pens, ruler and calculator. The students are requested to write in an understandable way, not with pencils; no additional pages must be added to the provided ones. Bags and backpacks must be left at the room exit. Students willing to withdraw must write "withdrawn" on the first page, give the exam text back to the teacher, then exit the room. Results will be communicated on the course web page by the end of the exams’ session; students can see their revised exam: date and place will be communicated on the course web page.
