Learning Objectives
The course will illustrate the physico-chemical and mechanical properties of the main classes of materials and the main industrial technologies for manufacturing. The students will be able to select suitable materials and manufacturing technologies for a specific product and to evaluate the different options as a function of requirements and costs.
Prerequisites
Basic knowledge of chemistry, physics and mathematics.
Teaching Methods
Ex-cathedra lessons
Further information
The slides shown during the lessons and other teaching aids will be uploaded on the Course homepage on the site e-l.unifi.it
Type of Assessment
Written examination (given time: 1 h 30 min) consisting in 10 open-ended questions, for which a synthetic report must be given, regarding the program treated during the course.
In particular, the student shall prove to know:
- the mechanical properties of materials and the test conditions used to quantify these properties;
- the different materials types (metals, polymers and ceramics) and their chemical, physical and mechanical characteristics, also with relation to the different chemical composition and microstructure;
- the manufacturing technologies used for the different materials types, which allow to produce objects with either low or high shape complexity;
- the characteristics of the metal alloys of widespread use, also as a function of chemical composition and of thermal or mechanical treatments.
The on-line registration on the examination site of the University of Florence is required to access the examination.
