摘要
Room temperature instrumented nano-indentation with a Berkovich tip was carried out on polycrystalline ZrB2. The orientation of the individual grains was mapped using electron backscattered diffraction. The anisotropy in properties was similar to 20% and similar to 7% for nanohardness and indentation modulus, respectively. The nanohardness decreased from basal towards prismatic orientation with a minimum at similar to 50-60 degrees and the indentation modulus increased with a maximum at similar to 70-80 degrees. The indentation modulus anisotropy, calculated by Vlassak-Nix model, shows similar tendency as the experimental values.
