Il corso si propone di fornire allo studente competenza della relazione tra microstruttura e proprietà dei materiali metallici tradizionali (acciaio, leghe non ferrose) e materiali metallici innovativi (acciai ad alta resistenza, superleghe, leghe a memoria di forma, vetrometalli). Verranno affrontati argomenti sulle leghe per applicazioni ad alta e bassa temperatura e per applicazioni ad alte prestazioni.
Gli argomenti includono:
Progettazione di materiali metallici innovativi
Leghe ferrose innovative. Acciai speciali (SS, Duplex, HSS, HSLA...) e ghise speciali (Silal, Nicrosilal, Ni-hard..). Aspetti metallurgici, composizione, proprietà e loro applicazioni.
Leghe non ferrose innovative. Leghe di alluminio, magnesio e titanio Superleghe a base di ferro, a base di nichel e a base di cobalto: aspetti metallurgici, proprietà e applicazioni.
Leghe emergenti e funzionali (compresi biometalli e leghe ad alta entropia). Leghe Ni-Ti e leghe Co-Cr-Mo. Applicazioni
Compositi a matrice metallica.
Processi di lavorazione e produzione tradizionale e innovativa (inclusa produzione multimateriale e additiva)
The course aims to give the student an insight in the relation between microstructure and the properties of classical (steel, non-ferrous alloys) and modern (advanced high strength steel, superalloys, shape memory alloys, metallic glasses) engineering metallic materials.
