Most of the research efforts on metallic nanolaminates have been based on cubic systems such as face-centered cubic (fcc) and body-centered cubic (bcc) metals, e.g. Cu(fcc)/Nb (bcc), Cu(fcc)/Ag (fcc), etc. It has generally been found that the strength (hardness) of such laminates is a strong function of the individual layer thickness (h). Since plastic deformation modes in hexagonal close-packed (hcp) metals can be very different from cubic metals, and many hcp metals have become increasingly important both technologically and scientifically, in this work, we prepared nanolaminates based on hcp metals such as Mg/Ti and Mg/Zr. The nanolaminates were prepared by magnetron sputtering. The microstructure of the specimens were characterized using TEM/XRD, and the mechanical properties of the laminates were evaluated using nanoindentation and microcompression. It was found that the mechanical properties of these nanolaminates are a strong function of h. Epitaxial grown between Mg and Ti has been identified.
