Obiettivo

The aim of the resear ch is to investigate the characteristics and the production processes of metal matrix (aluminium alloys) composites reinforced by short fibres or whiskers and by using powder metallurgy techniques. This technology is suitable for manufacturing extruded or forged composite structural components with high strength metal matrices. The programme envisages the following phases: Production and characterization of all powders and fibres. MMC sintering and extrusion. Forging and characterizsation of the finished part. This process complements both the squeeze casting, currently being considered for full commercialisation, and the diffusion bonding process which enables very high performance MMC reinforced with continuous fibres to be obtained but at high costs, therefore limiting their use to particular applications.

- PRODUCTION AND CHARACTERISATION OF ALL POWDERS AND FIBRES.
- MMC SINTERING AND EXTRUSION.
- FORGING AND CHARACTERISATION OF THE FINISHED PART.

THIS PROCESS COMPLEMENTS BOTH THE SQUEEZE CASTING, CURRENTLY BEING CONSIDERED FOR FULL COMMERCIALISATION, AND THE DIFFUSION BONDING PROCESS WHICH ENABLES TO OBTAIN VERY HIGH PERFORMANCES MMC REINFORCED WITH CONTINUOUS FIBRES, BUT AT HIGH COSTS, THEREFORE LIMITING THEIR USE TO PARTICULAR APPLICATIONS.
