Utilisation of fly ash as a potential reinforcement material for better mechanical properties of Aluminum

The remarkable strength and durability characteristics found in lightweight alloys-based Metal Matrix Composites (MMC) assisted in enhancing their widespread use in automobile, aircraft, and marine sectors. The present study consists of utilizing a conventional stir casting setup for fabricating Aluminium-based MMCs having fly ash as reinforcement. The fly ash was reinforced with an aluminum matrix in proportions: 2, 4, and 6 % to get three different homogeneous samples of MMCs. The prepared samples were examined for microstructure and mechanical characterization. The MMCs samples exhibited successful incorporation and homogeneous dispersion of fly ash particles. The fly ash addition assisted in enhancing the hardness and decrease in strength of aluminum MMCs.
