On the Crystallization of Terbium Aluminium Garnet
Attempts to grow terbium aluminium garnet (Tb3Al5O12, TAG) by the Czochralski method lead to crystals of millimeter scale. Larger crystals could not be obtained. DTA measurements within the binary system showed that TAG melts incongruently at 1840 ◦C. The perovskite (TbAlO3, TAP) with a congruent melting point of 1930 ◦C is the most stable phase in this system. The region for primary crystalliz...
متن کاملDirect Numerical Simulation of Solidification Microstructures Affected by Fluid Flow
The e ects of uid ow on the solidi cation morphology of pure materials and solute microsegregation patterns of binary alloys are studied using a computational methodology based on a front tracking/ nite di erence method. A general singleeld formulation is presented for the full coupling of phase change, uid ow, heat and solute transport. This formulation accounts for interfacial rejection/absor...
متن کاملINFLUENCE OF THE PRIMARY SOLIDIFICATION ON THE SECONDARY SOLIDIFICATION DURING SEMISOLID METAL (SSM) PROCESSING OF A356.0 ALUMINUM ALLOY BY MECHANICAL STIRRING
Abstract: The aims of this research were to investigate the effects of semisolid metal (SSM) processing parameters (i.e., shear rates –times – temperatures combinations) on the primary solidification products and isothermal holding duration, subsequent to cessation of stirring on the secondary solidification of Al-Si (A356) alloy. The dendrite fragmentation was found to be the governing m...
متن کاملSynthesis of Iron Yttrium Garnet Nanoparticles by Reverse Microemulsion Method
Colloidal nanodispersion of Iron Yttrium Garnet has been preparedbymixing the two ternary mixture of Triton X-100 (surfactant), n-heptane and aqueous solution that differing only in the aqueous phase.Ethanolwas added as cosurfactant and mixed them by ultrasound bath. By mixing these twomicroemulsions, Iron Yttrium garnet (Y3 Fe5 O12) nanodispersionwas obtained. Solids were settled by centrifuge...
