MATERIALS SELECTION IN ENGINEERING APPLICATIONS
Knowledge and understanding
At the end of the course the student will have integrated his knowledge about interactions between microstructure and properties and a complete overview of the physical and mechanical properties of different kinds of materials; will know the theoretical reasons to select chemical and physical treatments able to modify materials properties; will know how to choose the materials in relation to their properties, cost and sustainability.
Applying knowledge and understanding
At the end of the course the student will have developed the ability to understand physical and mechanical properties of materials, such as density, strength, ductility, toughness, elasticity, hardness, stiffness and resilience to the microstructure of different kinds of materials. He will know how to measure the values of each property, to compare the data with standards and to select criteria for final components optimization.
By the end of the course, the student should be able to evaluate, with critical mind, the chemical, physical and mechanical behavior of materials.
By the end of the course, the student must be able to clearly present the experimental results of materials behavior.
Ability to search tools and opportunity of knowledge approach.
Capability to study, to schematize and to resume the learned contents.
Basic knowledge of chemistry and physics.
The course is developed through a preliminary introduction to the main families of materials used in engineering applications, a subsequent deepening of the interaction between weight and stiffness, plasticity, yield and ductility and fracture and fracture toughness.
The aspects associated with rubbing, sliding and blocking (seizure), as well as friction and consuption will be investigated.
Furthermore, the properties of functional materials will be studied by evaluating their behavior under different operating conditions. In particular, the relationships between the chemical-physical characteristics of the individual materials and their thermal behavior will be explored.
The behavior of the materials will be studied through the evaluation of their durability as a result of phenomena such as: oxidation, corrosion and degradation.
In addition, the production processes will be deepened through the definition of heat treatments, machining by deformation, joining and finishing of the individual components.
Finally, the sustainability of the life cycle of materials will be assessed through the study of their interactions with the environment.
