Morphological instability of a nonequilibrium icecolloid interface [PDF]
, 2009 We assess the morphological stability of a nonequilibrium icecolloidal suspension interface, and apply the theory to bentonite clay. An experimentally convenient scaling is employed which takes advantage of the vanishing segregation coefficient at low ...

Advanced Engineering Materials, EarlyView.It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Nonequilibrium molecular dynamics simulation of rapid directional solidification
, 2000 We present the results of non-equilibrium molecular dynamics simulations for the growth of a solid binary alloy from its liquid phase. The regime of high pulling velocities, $V$, for which there is a progressive transition from solute segregation to ...

Directional solidification in two and three dimensions
Physical Review Letters, 1993 A symmetric phase-field model is used to study directional solidification in two and three dimensions. Numerical evidence of tip-splitting, breathing modes, solitary modes, and other non-steady-state behavior is seen in 2D. A simple model for the breathing modes is proposed. Finally, 3D simulations indicate a hexagonal ordering of cells.

Advanced Engineering Materials, EarlyView.Stabilization of L‐PBF Ni50.7Ti49.3 under low‐cycle loading was investigated. Recoverable strain after cycling was dependent on the amount of applied load. Recovery ratio was 53.4% and 35.1% at intermediate and high load, respectively. The maximum total strain reached 10.3% at a high load of 1200 MPa.

Lamellar orientation control in directionally solidified TiAl intermetallics [PDF]
China Foundry, 2014 TiAl-based alloys are potentially used as high-temperature structural materials with a high specific strength in the range of ~ 900 °C. However, the mechanical properties of TiAl-based alloys are extremely anisotropic with respect to the lamellar ...

On Directional Dendritic Growth and Primary Spacing—A Review
Crystals, 2020 The primary spacing is intrinsically linked with the mechanical behavior of directionally solidified materials. Because of this relationship, a significant amount of solidification work is reported in the literature, which relates the primary spacing to ...

In-situ observations of dendritic fragmentation during directional solidification of Sn-10wt.% Bi alloy [PDF]
China Foundry, 2019 The stray crystals seriously affect the properties of metals which fabricated by directional solidification (DS). In order to observe the formation of the stray crystals, the growth behavior of Sn-10wt.%Bi alloy was observed by synchrotron X-ray imaging ...

Capillary-wave description of rapid directional solidification [PDF]
Physical Review E, 2012 A recently introduced capillary-wave description of binary-alloy solidification is generalized to include the procedure of directional solidification. For a class of model systems a universal dispersion relation of the unstable eigenmodes of a planar steady-state solidification front is derived, which readjusts previously known stability considerations.
