Superhard materials are usually composed of light elementssuch as boron, carbon, nitrogen, and oxygen. These lightelemental atoms have the ability to form covalently bonded,three-dimensional networks of high atomic density withextreme resistance to external shear.

Comment on "Synthesis of Ultra-Incompressible Superhard Rhenium Diboride at Ambient Pressure"

The synthesis of superhard rhenium diboride (ReB2) at ambient pressure is shown to be not a superhard material, and the prospect for large-scale industrial applications of ReB2 doubtful.

Osmium diboride, an ultra-incompressible, hard material.

In this work, two design parameters are applied to identify ultra-incompressible, superhard materials-high valence electron density and high bond covalency and the first example of such a material is OsB2.

B6O‐Based Composite to Rival Polycrystalline Cubic Boron Nitride

The Vickers hardness of boron suboxide single crystals was measured using a diamond indentation method. Under a loading force of 0.98 N, our test gave an average Vickers hardness of 45 GPa. The…

Restricting Dislocation Movement in Transition Metal Carbides by Phase Stability Tuning

It is demonstrated, from first-principles calculations, that by suitable alloying the energy difference between several competing structures in the transition metal carbides is small or tunable, which creates multiphase/polytypic compounds with a random or controllable layer stacking sequence, allowing the possibility of a greatly enhanced hardness.
