Cellular and dendritic growth of HCP Zn-Cd alloys is strongly influenced by crystalline anisotropy, being fundamental in the fixing of the operative conditions during dendritic growth, and takes a fundamental role in the formation of cellular growth. Also, critical values of velocity and wavelength for planar to cellular transition changes slightly even for small misorientation between growth and preferential growth directions. In this work, directional solidification of HCP Zn-Cd dilute alloys were developed, for different solidification conditions, in order to obtain morphologies from planar to cellular and dendritic structures.
