| Abstract Scope |
Recycling Al is an up-to-date topic nowadays due to the economic benefit and sustainability, in fact recycled Al employs only 5% percent of the energy necessary for its extraction from bauxite ore, saving 9 ton of CO2 per 1 ton of Al recycled. In this research project the principles of fractional solidification have been applied to reduce the amount of impurities in model recycled Al alloys. A set-up based on isothermal squeezing of a semi-solid alloys has been developed and tested. The ultrasonic vibration applied to the semi-solid material has proven to enhance the purification achievable, up to 65% of reduction in the concentration. A number of potential impurities such as Fe, Si, Ni, Cu have been tested. The role of solute partitioning during the process has been evaluated and characterized through the use of CT scanning and modelling. |
