title = "Aluminum composite castings incorporating used and virgin foundry sand as particle reinforcements",
abstract = "Incorporating virgin and used sand from foundries into aluminum castings serves as a means toward recycling waste sand, reducing the cost and improving selected mechanical properties of castings. The present research differs from other published studies in this field because higher volume percentages of finer silica particles are incorporated in Al-alloys in the virgin and used state. Stir mixing is used to incorporate up to 20 vol% of sand and squeeze casting can be used to incorporate above 50 vol% of sand. SEM and XRD show some of the silica in the sand is converted to Al 2O 3, leading to higher hardness, stiffness and abrasion resistance in the castings.",
