Resumen:
The cellular and dendritic growth of Zn-Cd dilute alloys is directly influenced by crystalline orientation, the primary orientation being the <10{1}0> and eventually <0001>. In general, this information is absent during the description of planar to cellular transition.However, it has been experimentally shown that the critical velocity for stability limit, and the associated wavelength of the first unstabilities are different depending on growth direction. In this work the stability of the accelerated planar fronts of Zn-0.01% Cd samples, obtained using a Bridgman like device and the behavior against morphologicalstability theory has been compared.
