| Popis: | A thermally stable high-strength mesocomposite containing nano-sized particles of titanium diboride (TiB2) is obtained by combining methods of self-propagating high-temperature synthesis and quasi-dynamic high-velocity pressing. The use of self-propagating high-temperature synthesis ensured obtaining a hardening component of the mesocomposite — nanocomposite with a TiB2 particle size of ≈ 100 nm. The quasidynamic method of obtaining a material characterized by high deformations determines self-organization of the mesocomposite microstructure with an unchanged size of the hardening TiB2 particles in the inclusion structure. Mechanical properties of the mesocomposite are substantially better than the properties of the composite matrix. |
