DefectsPaper
MIT and ORNL derive a criterion for the onset of local remelting in the mushy zone. Its critical value is not an alloy constant – it changes along the solidification path and shifts noticeably even within a narrow composition range.
DefectsPatent
A patent application: where freckles show up on a trial casting, thin wax rods are attached to the pattern across or along the convection flow. The segregation channels move into these ribs, which are ground off afterwards.
SolidificationPatent
An SJTU application: ceramic-fibre plates at critical levels of the mould block vertical radiation and reduce front tilt. Lower freckle and stray-grain tendency is claimed.
