Carbide Nanoparticle Hardness: Hall-Petch Grain-Size Scaling

Watch a nanocrystalline WC-Co, TiC or SiC microstructure get harder as its carbide grains shrink toward the nanoscale, then soften again below a critical size as grain-boundary sliding takes over — a real Vickers indenter presses in to show the effect live.

Metallic and covalent carbide nanoparticles — WC, TiC, SiC — are prized for extreme hardness, and that hardness is not fixed: it depends strongly on how small the crystalline grains are. This simulator builds a 3D nanocrystalline microstructure for WC–Co, TiC or SiC, computes its Vickers hardness from the Hall–Petch relation as grain size shrinks, and switches to the inverse Hall–Petch softening branch once grains pass below a critical size where grain-boundary sliding takes over from dislocation pile-up. A real Vickers diamond indenter presses into the surface under an adjustable load, and its indent diagonal and depth are computed from the same hardness value the microstructure just produced.

⚙ Under the hood

Build a nanocrystalline WC-Co, TiC or SiC microstructure and watch its Vickers hardness rise with the Hall-Petch relation as grains shrink, then fall again below a critical grain size as grain-boundary sliding takes over, with a real Vickers indenter pressing in to show the effect.
