I have no personal experience in making as-cast MMC with fly ash as the dispersant, but Professor P.K. Rohatgi does. His contact info is available at the end of the article attached. Good luck!

There have been several efforts on employing fly ash as reinforcement in Al alloys. Please go through the attached publications.

Aluminum-MMCs play a major role in the improvement of mechanical and tribological properties.It already proved that the tribological properties increases with the volume percentage of flyash content. "Fly-ash" from metallic-industry is desirable for making a reinforcement materials.
