Mechanical properties of ultra-hard nanocrystalline cubic boron nitride

摘要

Nanostructure and mechanical properties of bulk nanocristalline cubic boron nitride have been studied by transmission electron microscopy and micro- and nanoindentation. The obtained data on hardness, elastic properties, and fracture toughness clearly indicate that nano-cubic (F (4) over bar 3m) boron nitride belongs to a family of advanced ultrahard materials.
