DETERMINATION OF THE CRITICAL FRACTION OF SOLID DURING THE SOLIDIFICATION OF A PM-CAST ALUMINIUM ALLOY

摘要

During the solidification of aluminium alloys, a flow of the interdendritic liquid through the mushy zone plays an important role in the feedability and shrinkage-driven porosity formation. Therefore, for almost all the studies about casting modelling, a good knowledge of the mushy-zone behaviour is necessary.
