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.

Restricting Dislocation Movement in Transition Metal Carbides by Phase Stability Tuning
- Materials ScienceScience
