Abstract:	In this work, the formation of arrays of tin nanorods by rapid solidification of Sn–Zn alloys followed by selective chemical or electrochemical etching was investigated. Alloys with compositions close to the eutectic point were quenched from the melt using planar flow casting under different cooling conditions. X-ray diffraction and field emission scanning electron microscopy revealed that hypoeutectic alloys form porous structures as a result of zinc dissolution, while eutectic and hypereutectic compositions yield ordered tin nanorods aligned along the heat flux direction. The dimensions of the rods were found to depend on the cooling rate and substrate temperature, with finer and more ordered arrays obtained under rapid crystallization and higher thermal gradients. These results demonstrate that controlled rapid solidification followed by selective etching enables the scalable synthesis of ordered metallic nanorod arrays with tunable morphology.
