Using magnetic field gradients to control the directional solidification of alloys and the growth of single crystals
There are various magnetic field based approaches to melt flow control that are used commercially to improve the quality of a crystal grown from the melt. Most of them are based on either a uniform or a rotating magnetic field. In this work, the effect of applying a suitably positioned magnetic field gradient on the growth of single crystals, particularly the interface curvature, growth rate an...
متن کاملCellular instabilities in directional solidification
2014 We have studied the morphology of the solid-liquid interface during the directional solidification of thin (5-150 03BCm) samples of a dilute binary mixture (CBr4/~ 0.1 % Br2) . Above a critical pulling speed, for a given temperature gradient and solute concentration, the interface, initially planar, breaks down into a periodic cellular pattern. The bifurcation from a planar to a cellular s...
متن کاملModelling of physical phenomena on Si melt during crystal growth process by Directional solidification method
Numerical simulation is a comprehensive tool in modern process development which is extensively used for promotion of crystal growth processes. Multi-crystalline silicon is an important material with advantages of low-production cost and high conversion efficiency of PV solar cells. The control of grains as well as the grain boundaries is particularly important to the crystal quality and thus t...
متن کاملOnset of sidebranching in directional solidification.
We use a computationally efficient phase-field formulation [B. Echebarria, Phys. Rev. E 70, 061604 (2004)] to investigate the origin and dynamics of sidebranching in directional solidification for realistic parameters of a dilute alloy previously studied experimentally [M. Gorgelin and A. Pocheau, Phys. Rev. E 57, 3189 (1998)]. Sidebranching is found to result either from noise amplification or...
متن کاملGrowth and Characterization of Single Crystals of Potassium Sodium Niobate by Solid State Crystal Growth
Due to the toxic nature of PbO in Pb(Zr,Ti)O3 (PZT), the most common type of piezoceramic, many studies on lead-free materials are being conducted worldwide (Röedel et al., 2009). One of the most studied groups of lead-free ferroelectric materials is based on a solid solution of potassium sodium niobate, K0.5Na0.5NbO3 (KNN) (Jaffe et al., 1971; Kosec et al., 2008). However, activity in attempts...
