Cutting Edge Process

Cutting Edge Process: Downward Directional Solidification
Downward directional solidification is a novel process that encompasses heat transfer, fluid flow, and solute transport mechanisms. These in turn affect the development of the microstructure and morphology of the phases. Effects on the direction of heat extraction, either downwards or upwards, during solidification of metallic alloys are rarely studied. This is a new approach to the solidification. Burden and Hunts were two scientists who carried out experiments with non-metallic alloys. They used NH4Cl/H2O in order to investigate the effects of downward and upward directional solidification on the dendritic growth of primary branches. Yes
