Summary on Grant Application Form
The programme develops a preliminary demonstration of the promise of the process. The main aim is to identify the principal process parameters in the simultaneous reaction synthesis and consolidation occurring during extrusion and to optimise these with respect to component microstructure and mechanical properties. Of major scientific interest is gaining an understanding of the mechanisms controlling the intermetallic synthesis and densification in order to establish the flexibility and potential of the process for the production of engineering components. The experimental approach will involve detailed chemical and microstructural characterisation of the material in both the extruded and heat treated forms in order to determine the kinetics of the phase transformations involved. The room and elevated temperature mechanical properties will also be characterised. A model of the engineering behaviour of these materials will be developed with a degree of sophistication dependant on the experimentally determined structure / property relationships. The major part of the experimental work will be carried out on the nickel-aluminium system. However, preliminary experiments will also be carried out to determine the feasibility of producing MMCs by this process and on the potential for extending the approach to other systems, such as titanium-aluminium and molybdenum-silicon.
