Chemical Engineering

The course is organized in two modules: a more general module of 8 CFU on materials science and technology (SSD ING-IND/22) and a module of 4 CFU more specifically dedicated to the themes of metallurgy (SSD ING-IND/21). The two modules are totally integrated with each other, and the program, with numerous interactions and frequent reciprocal recalls, is carried out in parallel with lectures evenly distributed throughout the teaching period. The program is developed in the following themes: - Introduction to Materials Science and Engineering - Atomic Structure and Bonding - Crystal and Amorphous Structures in Materials - Solidification, Crystalline Imperfections - Thermally Activated Processes and Diffusion in Solids - Mechanical Properties and Mechanical Testing of Materials - Phase Diagrams - Engineering Alloys - Polymeric Materials - Ceramics - Composite Materials - Fundamentals of Corrosion and Protection of Materials

- The exam of Chemistry represents a formal pre-requisite. - Knowledge of fundamentals of Organic Chemistry is very useful for a full understanding of the nature and properties of polymeric materials. - Knowledge of fundamentals of Physics and Structural Mechanics can be useful for the conscious and appropriate selection of materials endowed with the desired mechanical properties for components subject to different stresses, as well as for the understanding of characterization tests. - The ability to choose, integrate autonomously, ask and sometimes precede is a fundamental attitude for a future engineer.

Attendance, optional, takes place according to the classrooms and times established by the Presidency. Attendance, although strongly encouraged, does not contribute to the final evaluation

The assessment will be based on the results of an oral interview, aimed at verifying the acquisition of the following knowledge and skills: - knowledge of microstructure, properties, design, production and transformation processes, use, analysis, characterization and degradation of materials of interest for industrial engineering; - ability to apply this knowledge to select the materials suitable for different applications, to recognize the conditions of possible risk in operation, to choose the most appropriate tests to evaluate the performance of materials. One single interview is taken for the two modules. The first question, addressed to all students, concerns the "Fe-C state diagram". The minimum grade for passing the exam (18/30) is achieved only if the student demonstrates a sufficient degree of knowledge of the equilibrium conditions of the iron-based alloys for increasing carbon content, and of the relative microstructures, and if he/she shows to be able to discuss the fundamental correlations between such microstructures and the main mechanical and technological properties of steels and cast irons. For the final evaluation the following aspects will be considered: - the level of knowledge - the ability to securely correlate different topics - the ability of applying knowledge to the solution of problems of limited complexity in the field of materials engineering - the ability to communicate the acquired knowledge and to illustrate the technical solutions proposed with clarity using a proper technical vocabulary. In order to obtain the highest marks (30/30 cum laude), the student must demonstrate that he/she has acquired excellent knowledge of all the topics covered in the course, and that he/she can apply this knowledge to the solution of problems in the field of industrial engineering, proposing original solutions and showing the results of an autonomous extension of knowledge.

The activities are organized in: - face-to-face lectures (for the acquisition of knowledge) - exercises for the solution of engineering problems of limited complexity
