Impurity accumulation within the aluminum scrap cycle results in downgrading and
challenges the sustainability recycling. Aerospace-grade aluminum alloys demand stringent …

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

Melting or re-melting accompanies solidification in many technical castings. For example,
during ingot casting, some crystal fragments or equiaxed grains can enter the superheated …

During directional solidification of alloys in the microgravity environment of the International
Space Station (ISS), growth of dendritic array is expected to be under purely diffusive …

In this work, the effect of solute expansion coefficient on the natural convection and freezing
front propagation is investigated by performing three-side cooled solidification experiments …

It has been amply shown that porosity defects can degrade the mechanical properties of
solidified alloys. In particular, the presence of large pores or bubbles in the melt during …
