Metallurgia dei Metalli non Ferrosi
Metallurgy of Non Ferrous Metals Marcello Cabibbo
Fe-C phase diagram, CCT diagrams of steels, classificatipn of steels, base knowledge of cast-irons and aluminum alloys.
KNOWLEDGE AND UNDERSTANDING:
At the end of the course, students will be able to master the production processes, the main mechanical properties and characteristics of non-ferrous alloys and metals presented in the courseCAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING:
At the end of the course, students will have to: 1. acquire the skill to assess the main specific properties of the most diffuse non-ferrous metals and alloys; 2. know how justify the failure mechanisms of the non-ferrous alloys; 3. their corrosion resistance attitude and behavior; 4. to know the specific application fields and industrial scope of the non-ferrous alloys presented in the courseTRANSVERSAL SKILLS:
The proposed student reports on specific course topics will develop a self-supporting knowledge of the major arguments of the course, it will also contribute to develop a speak out skill of the students

Development of the examination
LEARNING EVALUATION METHODS
wrtitten and oral
LEARNING EVALUATION CRITERIA
The student will have to show a sufficient level of knowledge of all the topics included in this course.
LEARNING MEASUREMENT CRITERIA
base 30 points.
FINAL MARK ALLOCATION CRITERIA
The exam mark resuls from an aritmetic mean between the oral and the short report produced by the students during the class.
The oral exam consists of 3 queries each of them with a maximum mark of 10 points. Each of the 3 student reports sill be evaluated on a 10-point basis. The "lode" will be assigned to those students that will show excellent knowledge in all the three queries.
