Stephen H. Davis (1939–2021) was an applied mathematician, fluid dynamicist, and
materials scientist who lead the field in his contributions to interfacial dynamics, thermal …

Sea ice is a reactive porous medium of ice crystals and liquid brine, which is an example of
a mushy layer. The phase behaviour of sea ice controls the evolving material properties and …

Atom probe tomography (APT) and first-principles calculations are implemented to study the
partitioning of W to the γ (face-centered cubic)-and γ′(L12)-phases in Ni-based alloys. APT …

The microstructure and mechanical property of single crystal superalloy CMSX-4 fabricated
by downward direction solidification (DWS) and upward direction solidification (UWS) were …

Single-crystal nickel-based superalloys are used for turbine blades in jet engines and power
generators. During the solidification of these alloys, misoriented defects, namely freckles …

Single-crystal CMSX-4 superalloy bars were casted by using downward (DWDS) and
upward (Bridgman) directional solidification processes. The interdendritic segregation along …

Freckles are misoriented defects formed during the solidification of single-crystal (SC) nickel-
based superalloys, which are used for turbine blades in jet engines and power generators …

Atom-probe tomography (APT) and first-principles calculations are employed to investigate
the partitioning of Hf in the γ′(L 1 2)∕ γ (fcc) phases in two multicomponent Ni-based …

We study nonlinear, two-dimensional convection in a mushy layer during solidification of a
binary mixture. We consider a particular limit in which the onset of oscillatory convection just …
