Investigation of segregation and density profiles in the mushy zone of CMSX-4 superalloys solidified during downward and upward directional solidification processes

•Single crystal bars were quenched using downward and upward processes.•The segregation profiles along the mushy zone were examined and compared.•The corresponding density profiles were calculated and compared.•The density increases from dendritic tip to bottom in both quenched mushy zones.•By using...
