Learning objectives
Ability to apply knowledge and understanding:By using classroom or laboratory exercises related to some of the topics in the program, students learn how to apply knowledge acquired in a real context of industrial issues.Judgment autonomyThe student must be able to comprehend and evaluate critically all the alloying elements in the main classes of studied metals, thermal treatments, microstructure, mechanical and physical characteristics and main applications, so that they can be able to give directions on the choice of metallic material in the food industry design.Communication skillsThrough the frontal lessons and the comparison with the teacher, the student acquires the specific vocabulary inherent in the physical metallurgy and the main classes of metal materials for the food industry. It is expected that at the end of the course the student will be able to transmit the content of the course and the metallurgical problems in oral and written form.Learning abilityThe student who has attended the course will be able to deepen their knowledge in the field of metal materials 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.

Course unit content
The course discusses the main classes of metallic materials for the food industry (stainless steels, duplex and aluminum alloys) and nickel, copper, chrome and titanium hints for the purpose of understanding the different types of use. The first part of the course deals with fundamental metallurgy that will enable students to tackle the various metal classes in the program.
Full programme
Fundamentals of metallurgy: structure of metal materials, defects, deformability. Thermal Treatments and Strengthening Methods.Classes of metallic materials.Introduction to steels. Steels used in the food industry: stainless steels, duplex steels. Strengthening methods in steels. Features, uses, problems with degradation with examples.Introduction to aluminum and its alloys. Characteristics, uses, problems of degradation with case study. Reference Standard.Properties of Nickel and its alloys: Ni-Cu and examples of innovation.Copper, Chrome, Titanium and their alloys.Metallic coatings commonly used for food equipment.
Bibliography
The slides projected during the course are made available to students in pdf format for sending directly to their email address. The following texts are recommended for some of the topics discussed in the course: i) I.J. Polmear, Light alloys -Metallurgy of the Light Metals, 3 ed. Windworthworth-Heinemann, Oxford (2000)..
Teaching methods
The course is held in 6 CFUs, which correspond to 42 hours of lesson. The didactic activities will be carried out by privileging frontal classroom lessons in which the course topics will be discussed from a theoretical point of view, in order to facilitate the understanding of the various classes of metallic materials with particular emphasis on the relationship between the microstructure, mechanical properties and the corrosion behavior.
Assessment methods and criteria
Testing is performed with a written test and an oral exam. The written test is divided into 3/4 questions that may relate to the theoretical contents and / or the exercises dealt with during the course. The test is exceeded if it reaches at least 18/30. Oral exam is an integral part of the exam and concerns the written exam or other parts of the exam. The final vote can be increased by 5-6 points. ’30 cum laude’ is given if the maximum score is achieved and mastery of the disciplinary vocabulary is demonstrated.
