A novel boron-based superhard material produced at high pressures and temperatures

摘要

In the last few years the interest of researchers in searching for novel superhard phases has quickened. This is attributable, firstly, to the theoretical generalization of the accumulated experimental data on the relationship between the formation of structure and properties of materials produced under different conditions, including high pressures and temperatures, and the prediction on this basis of novel phases with a unique combination of physico-mechanical properties. Secondly, this is a result of the development of novel structural materials that require specific machining processes which can be implemented only by the use of new superhard materials.
