Grain Refinement Efficiency of a New Oxide-Containing Master Alloy for Aluminium Casting Alloys

Year: 2014

Type: article

Abstract: In this study, grain refinement efficiency of a new oxide master alloy based on MgAl2O4 was demonstrated on an A357 alloy. The grain size of the reference alloy was reduced by 50-60% with the addition of the master alloy and introduction of ultrasonic cavitation. A higher addition of master alloy was found to be not benificial in further reducing the grain size.
