Room temperature deformation behaviors of ZrB2 micropillars, fabricated by focused ion beam technique from differently oriented grains of polycrystalline ZrB2, were investigated under micro compression. Considerable anisotropy was found showing ~80% higher yield (σY) and rupture (σr) stress values for the basal oriented pillars (σY,basal=13.4 GPa, σr,basal=13.4 GPa) compared to the prismatic pillars (σY,prism=6.4 GPa, σr,prism=7.6 GPa). Micro-scale plasticity was detected in prismatic oriented pillars, revealing the activation of the {101-0}〈112-3〉 type slip system both in the form of single- and multiple-slip which is anomalous for ZrB2 and has not been reported so far in the relevant literature.
