In this work, the anisotropy of elastic and plastic properties of pure magnesium are investigated using spherical indentation stress strain analysis on grains of different orientations in a polycrystalline sample. The measurements show variations in indentation elastic modulus (Eind), indentation yield strength (Yind), and indentation hardening rate (Hind) as function of the grain lattice orientation. In addition, length scale effects were studied over wide range of indenter sizes: 1, 16, 100, and 500 Ám (radius) on multiple grain orientations. This study provides new insights into slip and twin activities in plastic deformation of pure magnesium at different length scales.
