Recycling Mechanism of Discontinuously Reinforced Al Matrix Composites

Article Preview

Abstract:

In the present work, the effects of reinforcement type, reinforcement surface treatment, alloying additions, remelting time and remelting number upon the chemical and property degradations of discontinuously reinforced Al matrix composites, are investigated by means of Differential Scanning calorimeter (DSC), Transmission Electron Microscopy (TEM) and thermodynamic calculations. The results show that the SiCp/Pure Al and SiCp/wrought Al alloy composites could not be recycled via remelting, nevertheless SiCp/foundry Al alloy and Al2O3p/Al composites could be recycled via remelting. The remelt-recycling mechanism of discontinuously reinforced Al matrix composites is also discussed in detail in the present work.
