Abstract

The reutilization of waste materials into novel products is widely recognized as a challenge of high technologic interest. This investigation aims to sustain fly ash as a suitable ceramic preform for the production of MMCs by liquid metal infiltration of a high-alloyed aluminum (AA7075). The effect of a series of production parameters on the resulting microstructural homogeneity of the MMC is quantified. The influence of binder concentration preform dimension and orientation are evaluated among others. Starting materials, preform, and final product are examined by optical microscopy, SEM, EDX, and XRD indicating the developing structures and dominating phenomena throughout the manufacturing process.
