Abstract
The eutectic morphology of in Al-5Ce alloy was tuned from lamellar to fiber using permanent magnet stirring (PMS) during casting. Superior mechanical properties were achieved in Al-5Ce alloy with fiber structure. Lamellar-to-fiber transition is quantitatively modeled within Jackson–Hunt framework. This is the first observation of producing fiber structure of Al-5Ce alloy during permanent mold casting, which sheds light on utilizing PMS to improve mechanical properties of Al-Ce alloys.
