Solidification Mechanisms in Melt Conditioned Direct Chill (MC-DC) Cast AZ31 Billets

Abstract:

The solidification mechanism in the melt conditioned direct chill (MC-DC) casting process was investigated by pouring liquid Pb into the sump during the casting process. This preserved the solidification front for subsequent metallographic examination. The results demonstrated that the solidification in the MC-DC casting process was preceded by the sedimentation of rosettes, which were nucleated in the sump and then grew under intensive melt flow.
