Summary on Grant Application Form |
|
Semisolid processing of metallic melts is an area of increasing technological importance in the near net shape forming of materials such as superalloys, tool steels and metal matrix composites. Yet at the theoretical level, the complex interaction between microstructure and rheology means that the behaviour of these materials is very poorly understood. A joint program of experimental and theoretical investigation is proposed to address this problem. The experimental investigation will focus on the study on analogue systems which have a transparent liquid phase, primarily NH4CL and H20 and will utilise laser particle sizing and high speed video to observe directly changes in grain size and morphology during a variety of processing operations, including rheological characterisation. This will be coupled with a theoretical investigation which will look at the fluid dynamics of processing mushy solids, focusing on novel approaches to relating processing conditions to changes in microstructure and hence to rheology. In this respect the cellular automaton approach, which has had considerable success in bridging the divide between processing conditions and microstructure in other areas of solidification modelling, coupled to conventional CFD and particle tracking techniques could prove particularly useful.
