Science and technology of materials/Technology of metallic materials (Science and technology of materials)

The primary aim of this course is to give students basic knowledge of materials, microstructure and processing technologies of interest for automotive and mechanical engineering. The properties of the main classes of materials will be presented, in particular their mechanical and thermal properties. Special attention will be given to steels, cast irons and Al alloys along with their manufacturing processes. Applications of selected classes of steels, Al alloys, cast irons will be discussed, together with the main classes of polymers, aiming to guide students toward material selection, design and quality assessment.

The STM the exam consists in a written test on EXAM platform based on four questions and/or exercises similar to those done during STM lectures and covering all the STM program; Results will be communicated on the course web page by the end of the exams’ session; rules are given by Politecnico di Torino rules for online exams. Students who pass STM examare able to hold their score. Only when both exams (STM and TMM) are passed, the final mark, which results from the average of both exam marks, will be formally recorded on the student’s electronic "libretto". 18/30 is the minimum to pass each 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 evaluator.

Science and technology of materials/Technology of metallic materials (Technology of metallic materials)

The oral exam consists in three questions: a) the fundamental question, b) the engineering question, and the c) cross-link question. The overal oral exam duration is 30 min. The fundamental question concerns the knowledge of the equilibrium Fe-Fe3C phase diagram and the non-equilibrium TTT and CCT diagrams with special reference to the application of the phase rules in order to estimate microstructure composition on cooling. These diagrams are given to students in a graphical form by sharing the teacher's display with the students' ones. The student utilizes the public chat to give his/her answers. Only if this question is answered correctly, the exam proceeds with the second question. This question is taken from a total of 200 self-assessment questions associated to MMT lessons. Occasionally, a cross-link question will be given for achieving the highest mark which assess the capability of the student to cross-link different parts of the course to clarify actual metallurgical phenomena by cross-linking microstructure to manufacturing and mechanical properties.
