Abstract:
Semi Solid Metallurgy is a near-net-shape manufacturing process that has been identified to possess numerous process advantages. While SSM is already a viable manufacturing method, it is still under intensive development and critical breakthroughs are still much expected. Merton C. Flemings, the founder of semi solid metallurgy identified the path forward to achieving the much expected breakthroughs. The identified some key research directions include: the formulation of better understanding of the mechanism whereby desired microstructure for SSM forms. Development and full application of mathematical models as related to SSM is also seen to be very vital. In this present study, theoretical expositions are made on mechanism of evolution of desired microstructure in SSM. The influence of temperature, intermetallics and furnace design during thixocasting on the SSM structure is also mathematically elucidated.
