Journal papers, reports and reviews. A laboratory study is a reason to test, not a shop-floor instruction.
DefectsPaper
A Beijing group proposes ranking porosity tendency by two properties of the last liquid – the solid–liquid density difference and its viscosity – via Darcy's law.
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.
CoresPaper
Tianjin University and BIAM: with 15% kyanite and sintering at 1225 °C, the printed core's sintering shrinkage fell to 3.06% and its sag at 1540 °C to 0.82 mm.
SolidificationPaper
Molten metal from the seed runs into the gap and freezes as a chilled layer. With a 0.3 mm gap the casting stays single-crystal; with 1.0 mm, stray grains grow out of the layer.
Shells and patternsReview
Hot water, hot air, superheated wax, polyglycols, boilerclave steam, microwaves, dissolving salt patterns – what each method means for shell cracking, wax recovery and safety.
SuperalloysPaper
VIAM ran a three-factor designed experiment on a UVNK liquid-metal-cooling furnace and obtained regression models for yield, orientation and PDAS.
SolidificationPaper
In an industrial Bridgman furnace the side of the rod next to the chill ring, where the axial gradient is highest, had a coarser PDAS than the centre. The tilt of the liquidus isotherm matters, not just G and v.
