Evidence for tip velocity oscillations in dendritic solidification.

چکیده
Dendritic growth experiments were conducted in the reduced-convection environment aboard the space shuttle Columbia on STS-87. Spectral analysis was performed on 30-frame/s video data during growths of isothermal dendrites. Results indicate that pivalic acid dendrites exhibit a subtle oscillatory behavior of the axial growth velocity near the tip, with a frequency component that is associated with the sidebranch formation process.

Sensitivity analysis of dendritic growth kinetics in a Bridgman furnace front tracking model
A directional solidification experiment of a Ti–Al–Nb–B–C alloy by power down method is simulated using a Bridgman furnace front tracking model. The effect of varying the dendritic growth parameters; C, the columnar dendrite growth coefficient, and n, the undercooling exponent, is investigated. A matrix of growth coefficients and undercooling exponents at three levels each, based around a growt...
متن کاملA Deterministic Mechanism for Side-branching in Dendritic Growth
In this paper, we suggest a deterministic mechanism for the generation and development of sidebranches in dendritic growth. We investigated the existence of such a mechanism for Gibbs-Thomson-Herring (GTH [1]) anisotropic capillary boundary condition recently in our previous work [2] . Here, we focus our study on the GTH anisotropic kinetic boundary condition. We develop and apply accurate boun...
متن کاملDegenerate seaweed to tilted dendrite transition and their growth dynamics in directional solidification of non-axially oriented crystals: a phase-field study
We report the results of a phase-field study of degenerate seaweed to tilted dendrite transition and their growth dynamics during directional solidification of a binary alloy. Morphological selection maps in the planes of (G, Vp) and (ε4, Vp) show that lower pulling velocity, weaker anisotropic strength and higher thermal gradient can enhance the formation of the degenerate seaweed. The tip und...
متن کاملVelocity and radius transients during pressure mediated dendritic growth of succinonitrile
This study was part of a larger effort called the transient dendritic solidification experiment (TDSE), which uses the well known Clapeyron effect to study transient effects in dendritic solidification. The transient behaviour was studied between well defined steady states using pressure mediated changes since it is almost impossible to study the transient behaviour during growth of a dendrite ...
متن کاملThermoelectric magnetohydrodynamic effects on the crystal growth rate of undercooled Ni dendrites
In the undercooled solidification of pure metals, the dendrite tip velocity has been shown experimentally to have a strong dependence on the intensity of an external magnetic field, exhibiting several maxima and minima. In the experiments conducted in China, the undercooled solidification dynamics of pure Ni was studied using the glass fluxing method. Visual recordings of the progress of solidi...
