Training objectives
- Aim of the course is to give knowledge regarding the choice and application of engineering metallic materials. For a proper design of mechanical components and a better in-service application of metallic materials, students must have a deep knowledge of the influence of metallurgical processes (fabrication, tooling, joining and thermal treatment) on the microstructure of metallic alloys, and therefore on their mechanical properties.
Prerequisites
- The student must have the base knowledge of metal science and metallurgy and the knowledge regarding the microstructural properties of metallic alloys.
Course programme
- Aluminium and light alloys; wrought and casting Al alloys and processes; production technologies; classification according UNI EN standards. Al-Li alloys; aluminium alloys obtained by powder metallurgy; superplastic forming of aluminium alloys. Thermal treatments of Al alloys and critical parameters; defects of thermal treatment and fracture processes. Metallurgical aspects of traditional and advanced casting processes. Influence of microstructural parameters and casting defects on fatigue properties. Hot isostatic pressing and mechanical properties of Al casting alloys.
Metal matrix composites: long or short fibre and particles reinforcements. Microstructural and mechanical properties; industrial applications. Production techniques of MMC in the solid and the liquid phase: diffusion bonding, powder metallurgy, compocasting. Lanxide process.
Powder metallurgy (chemical, electrochemical and mechanical processes of powder production; forming; pressing; sintering).
Magnesium and alloys: properties, production technologies, thermal treatments, applications.
Titanium and alloys: properties, production technologies, thermal treatments, microstructural transformations and applications.
