Forced convection and its effect on the microstructure evolution of an Al-7wt.% Si alloy
during unidirectional solidification were studied experimentally. Under natural convection …

The volume-averaged solidification model has generated considerable research interest in
metallurgical areas. The model is complicated but flexible to address many problems faced …

Research efforts have been dedicated to predicting microstructural evolution during
solidification processes. The main secondary arm spacing controls the mushy zone's …

Strand electromagnetic stirring (SEMS) is widely applied in thin slab continuous casting to
improve the equiaxed crystal ratio (ECR) of steel. To provide a deeper insight into the role of …

Segregation channels with misoriented spurious grains, known as freckles, are an
unacceptable casting defect in superalloy turbine blades. A digital-twin method to predict …

A mixed columnar-equiaxed solidification model was recently extended to capture the
capillary-driven fragmentation phenomenon, which was considered the only mechanism for …

Making clear the metallurgical transport behaviors during direct chill (DC) casting is of great
significance to control the solidified structure and reduce the casting defects, but it still …

The effects of permanent magnetic stirring (PMS) on the dendrite fragmentation behavior
during the solidification of GH4742 superalloy were in situ investigated and the mechanism …

The use of freeze linings to protect pyrometallurgical furnaces from chemically corrosive
molten slags is a widespread technique in industrial processes. The main goal of the …

Freckles, a significant issue encountered during the directional solidification of superalloys,
are recognised by a trail of equiaxed grains parallel to the direction of gravity accompanied …
