Abstract
The synthesis of ultrahard nanocrystalline phases is based on the occurrence of direct phase transformations in carbon and boron nitride at high pressures during shock compression. This survey examines the relationship between features of the initial layered structures, the mechanisms of the direct transformations (martensitic, diffusional), and the actual structure of the ultrahard phases formed during shock compression.
