Ing Ind - Inf (Mag.)(ord. 270) - MI (491) MATERIALS ENGINEERING AND NANOTECHNOLOGY - INGEGNERIA DEI MATERIALI E DELLE NANOTECNOLOGIE
091607 - MATERIALS FOR ENERGY
The course is aimed at
-supplying organized knowledge of material classes specifically developed for applications in the energy sector (power generation and distribution, oil & gas, renewable energy systems, etc.) or materials applied in it due to specific properties
-supplying info about material damage forms specific of parts applied in the energy sector, methods for material damage evaluation and criteria for developing materials suitable to these damage form, also when concurrent.
-focusing on different features of the same engineering application, linking material selection to specific needs not only in terms of material performance, but also on process requirements, design requirements, service needs, costs etc.
Risultati di apprendimento attesi
At the end of the course the student:
- knows the materials (mainly structural) specifically developed for applications in the energy sector.
- is able to predict the main damage forms that could develop under specific conditions in a component working in the energy sector and to suggest possible materials to be used, or to evaluate modifications in service conditions, geometry, processes, heat treatments to prolong the life of the part;
- is able to critically analyze pieces of information on materials and their processes/performances obtained from different sources.
The course deals with the criteria for a proper choice of materials in the energy sector (power generation and distribution, oil & gas, renewable energy systems, etc.). In these plants and equipment, the materials must be able to meet the severe requirements given by hostile environments for a sufficient time span; at the same time the costs associated with the life-cycle of the product (design, manufacturing, service, maintenance and dismissal/recycling) should be kept to a minimum. Issues related to properties and manufacturing of turbine, engines, heat exchangers, filters, pipings, valves, blades, cables, etc. will be addressed, with a concurrent engineering approach. The specific requirements to the material for specific applications, the range of materials and processes to for these applications and the consequences of the choice on the component reliability, operating conditions will be examined. Many of the materials in the specific components examined are selected thanks to their structural properties, while in many others the key factor for material selection is a good combination of structural and functional properties (thermal, electrical, triboligical, etc..).
The course will be dedicated to the choice of materials suitable for applications in the energy industry. Different material classes and their processes will be proposed concurrently with their interrelations with the typical component needs, the process technologies adopted for their construction and the typical degradation processes taking place during their service. Thus the course, characterized by a concurrent engineering approach, will be organized by focusing on several reference components relevant for and typical of the field of energy engineering. Each item will give the opportunity to present their specific material classes, component requirements, development of manufacturing cycle suitable for good combination of mechanical and functional properties, material degradation phenomena, material science concepts transfer to standards for material selection or testing.
