Removal of Convective Instabilities in Liquid Metals by Centrifugation,eriments on molten tin show a reversible transition from an unstable to a stable regime, at a well defined value of the rotation rate. These observations can be understood by considering that the axial buoyancy force depends on both the density gradient and the acceleration generated along the axis

Growth of GaAs Single Crystals at High Gravity,avity conditions. Temperature oscillations in molten Sn indicated that the conditions used to grow GaAs single crystals showed depressing temperature oscillations. A possible reason is given for the increase of dislocation density of GaAs with increasing centrifugal force in a sandblasted quartz boa

Response of Temperature Oscillations in a Tin Melt to Centrifugal Effects,emperature gradient was applied to an open boat containing molten tin so that convection was generated with a known direction of the basic flow. The experimental results demonstrated that both effects of centrifugal and Coriolis forces exist due to the rotation of the centrifuge. The former enhances

The Influence of Gravity on Pb1-xSnxTe Crystals Grown by the Vertical Bridgman Method,s the convection, and the final solute distribution corresponds to the partial diffusion-convective mechanism. Also shown are results of high-gravity gradient freeze growth with a destabilizing temperature gradient.

Microstructural Development in Pb-Sn Alloys Subjected to High-Gravity during Controlled Directionalmaterials properties.. With the potential of such processing demonstrated, there exists a need for quantitative data gathered under controlled solidification conditions. To this end, a centrifuge, ., was constructed within the Materials Science and Engineering Department at Vanderbilt University. Th

The Role of Thermal Stress In Vertical Bridgman Growth of CdZnTe Crystals,Te crystals. Companion experimental studies included the growth of crystals grown with the same process parameters and the same geometry as the process modeled in the computations. Characteristics of the crystals grown were compared with the computational predictions. Predictions of growth ampoule o

Morphological Stability of Directional Solidification in a Centrifugal Field, forces. Temperature field is assumed to be a linear function and a vector of an angular rate is perpendicular to a growth direction. It is shown that the effect of Coriolis force has a dual character. At first, increase of Coriolis force lead to an instability of crystallization front. But when Tay
