It is typically determined by pressing the indenter into the test sample ... and boron carbide (B 4 C) to demonstrate that the hardness model works for hard and superhard materials.

Understanding the mechanisms of abrasive wear and developing effective testing ... silicon carbide (SiC) particles causing more wear than alumina (Al2O3) due to their greater hardness.

Space exploration pushes materials to their limits. From the intense vacuum of space to extreme temperatures and radiation exposure, the conditions are unlike anything experienced on Earth.

Grain size remains a critical factor in determining tungsten carbide’s properties: Fine Grains (0.5 µm): Provide high hardness and wear resistance, essential for cutting and drilling tools. Coarse ...
