Chapter 5.2 Effect of ball milling on compacting characteristics of Al-10% Al2O3-fly ash composites
-
Abstract
Aluminum metal matrix composites (AMMCs) are widely used because of their superior properties compared to aluminum (Al) and its alloys. The AMMCs find wide application in aerospace, automobile, and other industries. Fly ash, a particulate waste material produced in thermal power plants, need to be potentially used to reduce its effect on environment. In the present experimental study, Al-10 wt% alumina(0-15 wt%) fly ash hybrid metal matrix composites are prepared by ball milling and powder metallurgy technique. The compacting characteristics like ejection pressure, green density, percentage porosity, and compressive strength are reported. The ejection pressure of the composites increases with increase in milling time and wt% of fly ash. The green density decreases with the increase in milling time and wt% of fly ash. The 5 wt% fly ash composite has maximum compressive strength compared to other composites and also the strength increases with increase in milling time up to 3 h and thereafter decreases.
