(a) Schematic diagram of the Vickers indenter and the direction of the compressive stress (σ) and shear stress (τ) exerted onto the sample by each pyramidal plane (planes labeled as 1, 2, 3 and 4); (b) activation stresses for the dominant deformation modes as a function of the tilting angle of basal poles (Φ) with respect to the ED.
