As part of an investigation into potential soldering alloys, studies have been made on rapidly solified commercially pure (99.9%) and high purity (99.999%) zinc. Significant differences in structure are observed between these two materials. At high purity, a bamboo grain structure, together with a strong preferred orientation, is found across the ribbon thickness. By comparison, commercially pure zinc displays a smaller grain size with the development of a “eutectic” like structure consisting of regular lamellae. It is proposed that this occurs by the alignment of dislocation networks parallel to the zinc basal plane and perpendicular to the solid-liquid interface, in a similar manner to that seen in conventional studies on single crystals.
