Ideal shear strength is an important parameter that represents the strength of the material. We have performed first principle calculations of ideal shear strength for the (0001)[11-20] (basal), (0001)[10-10] (basal along partial direction), (10-10)[11-20] (prismatic) and (10-11)[11-20] (pyramidal) slip system of pure Mg. Later on effect of solutes (Al, Li, Zn, Zr, Y, Sr, Ce, Gd) on the ideal shear strength of magnesium was investigated. The present calculations showed that the ideal shear strength is maximum for the (0001)[11-20] (basal) and minimum for the (001)[10-10] (basal along the partial direction) system for pure magnesium. Addition of solute atoms improves the ductility of magnesium alloys due to activation of additional slip systems. The electronic structure calculations further explain the ideal shear strength mechanism for magnesium and its alloys.
