Learning objectives
Knowledge and ability to understand: through the frontal lessons learned during the course, the student will acquire the methods and knowledge about the plastic deformation mechanisms that determine the mechanical behavior of metallic materials at different working temperatures and on recent methods of manufacturing metal components such as additive manufacturing. Ability to apply knowledge and understanding:through practical classroom or laboratory exercises related to some topics in the program, students learn how to apply knowledge acquired in a real context of industrial issues.Judgment autonomyThe students must be able to understand and critically evaluate the link between microstructural and process parameters so that they can simulate deformation process even under unmanaged operating conditions. They also want to give directions on the choice of innovative production technologies for the production of metal components. Communication skillsThrough the frontal lessons and the comparison with the teacher, the student acquires the specific lexicon of mechanical metallurgy. It is expected that at the end of the course, the student will be able to transmit, in oral and written form, the content of the course and the problems of mechanical metallurgy.Learning abilityThe student who has attended the course will be able to deepen his / her knowledge in the field of mechanical metallurgy through the autonomous consultation of specialized texts, scientific or divulgative journals, even outside lecture topics, in order to effectively address entering into the labor market or undertaking further training paths
Prerequisites
Metallurgy skills.
Course unit content
The course proposes the close correlations between structure and mechanical properties of innovative metallic materials according to the production process and their terms of use in order to design high-performance metallic components. To this end, the course proposes the study of plastic deformation mechanisms that influence the mechanical behavior of metallic materials at room and high temperatures. A part of the course is devoted to the structures and properties of innovative welding techniques, and metal components produced by 3D printing. One part is dedicated to the study of metal alloys for the Automotive and Aerospace industries. Various case studies and/or workshops related to the topics of automotive and aerospace will be presented and discussed.
Full programme
Behavior of metals to deformation at room T and at high temperatures with review of diffusive processes, recovery and recrystallization phenomena and constitutive equations.
Creep and superplasticity: tests, theoretical formulation, methods to increase the creep resistance of a metal; examples.
The metallurgy of welding and innovative welding processes; properties and problems of joint areas; case studies of steels and light alloys.
3D printing of metal components (Additive Manufacturing of metals): printing processes, process variables, microstructure, and consequent properties in metal components; case study of alloys for the automotive and aerospace industries.
Metal alloys for the Automotive and Aerospace industries: study of Aluminum alloys, Titanium alloys, Nickel superalloys and related structural and use characteristics.
Bibliography
The slides projected during the course are made available to students in pdf format at Elly web site. Bibliographic insights will be recommended by the teacher at the end of each topic.
Teaching methods
The course is held in 6 CFUs, that correspond to 48 hours of lesson. The didactic activities will be held in classroom and in lab. The topics of the course will be addressed from a theoretical point of view, to improve the understanding of the issues in detail. Exercises and lab experience will be conducted on samples obtained by innovative technologies.
Assessment methods and criteria
The exam is a written test, composed of three-four questions related to the theoretical contents and exercises carried out during the course. The test is passed if the grade is at least 18/30. The grade ’30 cum laude’ is granted when the maximum score is achieved, and a strong command of the discipline terminology is achieved.
